+README for Paludis
+==================
+
+Paludis is in the really early prototype not intended for real use stage. If you
+aren't comfortable with C++, ebuild internals and Gentoo in general then you
+shouldn't be touching it.
+
+Developer documentation is available via 'make doxygen' (you need Doxygen
+installed, and having GraphViz will help too). It will be created under
+'doc/html/'. User documentation is kept in the bottom of a locked filing cabinet
+stuck in a disused lavatory with a sign on the door saying 'Beware of the
+Leopard'.
+
+If you don't feel like building your own docs, see:
+
+    http://paludis.berlios.de/

+\page BootstrapHowto Bootstrap Howto
+
+\section BootstrapHowtoMain How to make a Paludis chroot
+
+\warning READ EVERYTHING CAREFULLY, OR YOU WILL BREAK YOUR SYSTEM!
+
+<b>THIS WILL PROBABLY NOT ACTUALLY WORK!</b> Paludis is at the very
+early alpha stage.  It can sometimes install things, if you're very lucky, and
+if you're really lucky it might let you upgrade or uninstall them too. There are
+zillions of things that are not implemented. There are zillions of things that
+Paludis does differently from Portage -- some of these are intentional, some are
+not.
+
+You should join the <code>#paludis</code> channel on Freenode. If you're doing
+anything development-related, you should probably also ask to be allowed to
+subscribe to the <code>paludis-sekrit</code> mailing list.
+
+\warning Do not try to use Paludis and Portage to install things inside the same
+    root. The config and vdb formats are not compatible!
+
+\section BootstrapHowtoRequirements Requirements
+
+Install Paludis locally, being sure to configure <code>sysconfdir</code> as
+<code>/etc</code> to avoid confusion later on. There's an ebuild
+<a href="http://svn.berlios.de/viewcvs/%2acheckout%2a/paludis/overlay/sys-apps/paludis/paludis-0.ebuild">here</a>.
+
+You'll need libebt, eselect and Subversion. You'll also need either g++-3.4,
+g++-4.1 or some other reasonably standard C++ compiler along with a complete
+standard library implementation (so no uClibc++). If you're trying to run on
+non-Linux, you'll also need to fix a few includes and submit a patch.
+
+Make sure the test suite passes (either <code>FEATURES="test"</code> for
+Portage, or <code>make check</code>). If it fails, don't continue until you
+figure out why.
+
+\section BootstrapConfiguration Configuration
+
+Set up a local bootstrap config directory. We're assuming in this document that
+you're using <code>/mychroot</code> as the root path, but anywhere not on a
+noexec / nodev filesystem should work. The reason for doing things this way will
+become apparent later on.
+
+\verbatim
+mkdir ~/.paludis-bootstrap
+cat <<END > ~/.paludis-bootstrap/specpath
+root = /mychroot
+config-suffix =
+END
+\endverbatim
+
+Make some skeleton directories and files:
+
+\verbatim
+mkdir -p /mychroot/etc/{env.d,paludis/repositories}
+mkdir -p /mychroot/var/{db/pkg,paludis/repositories/gentoo/distfiles}
+mkdir -p /mychroot/tmp/
+touch /mychroot/etc/ld.so.conf
+\endverbatim
+
+Set up your <code>keywords.conf</code>. At the very least, you'll need a <code>*
+keywords</code> line.  Further lines can be added in the form "atom keywords".
+Like with Portage, accepting <code>~keyword</code> does <b>not</b> accept
+<code>keyword</code>, so if you want a fully <code>~arch</code> system you
+should use <code>* arch ~arch</code>.
+
+\verbatim
+cat <<END > /mychroot/etc/paludis/keywords.conf
+* x86
+dev-cpp/libebt x86 ~x86
+sys-apps/paludis x86 ~x86
+dev-util/subversion x86 ~x86
+app-admin/eselect x86 ~x86
+app-editors/vim x86 ~x86
+app-editors/vim-core x86 ~x86
+END
+\endverbatim
+
+Set up your <code>use.conf</code>. At the very least, you'll need a <code>*
+flags</code> line. Again, additional per-atom lines can be specified. The
+<code>-apache2</code> is important, if you value your sanity, since you'll be
+installing subversion. We're experimenting with a slightly different way of
+handling <code>USE_EXPAND</code> variables that allows different settings for
+different packages. This may change, but for now it looks like this:
+
+\verbatim
+cat <<END > /mychroot/etc/paludis/use.conf
+* -doc nls -apache2 LINGUAS: en INPUT_DEVICES: keyboard mouse VIDEO_CARDS: ati
+app-editors/vim -nls
+END
+\endverbatim
+
+Set up your <code>licenses.conf</code>. If you don't care about licences, which
+is probably wise until we get licence grouping, it should look like this:
+
+\verbatim
+cat <<END > /mychroot/etc/paludis/licenses.conf
+* *
+END
+\endverbatim
+
+If you want some more fun, the following list might be enough to install a
+base system if you don't turn on too many extra USE flags:
+
+\verbatim
+cat <<END > /mychroot/etc/paludis/licenses.conf
+# These are the basic system requirements. It's possible to knock off
+# a few of these by turning off some default USE flags.
+* LGPL-2.1 LGPL-2 GPL-2 BSD MIT BZIP2 Artistic DB PSF-2.1.1 PSF-2.2
+* as-is tcp_wrappers_license freedist ZLIB openssl CRACKLIB PAM FLEX
+
+# These are needed to get Subversion.
+* Apache-1.1 Apache-2.0
+
+# These are needed to get an editor that doesn't suck.
+* vim
+
+# These are needed if you want modular X. This is utterly ridiculous,
+# and the people responsible for using different licence IDs for
+# identical licences should be shot.

+END
+\endverbatim
+
+Set up your <code>package_unmask.conf</code> and <code>package_mask.conf</code>,
+if necessary::
+
+\verbatim
+cat <<END > /mychroot/etc/paludis/package_unmask.conf
+app-editors/vim
+app-editors/vim-core
+END
+\endverbatim
+
+Set up your <code>bashrc</code>. This must <b>NOT</b> be used to change any
+values that affect dependency resolution (e.g. <code>USE</code>,
+<code>LINGUAS</code>). It can be used to set <code>CFLAGS</code>,
+<code>CHOST</code> and the like (on some archs you'll have to do this to
+avoid getting junk from your profile). Remember to <code>export</code> your
+variables.
+
+Unfortunately, some packages in system have broken test suites, and some
+packages abuse non-${ROOT} locations in pkg_postinst. Thus, you will also
+need to add a bit of magic to work around these packages.
+
+\note The backslash before the dollar is for cat. If you're not using cat,
+   don't include the backslash before the dollar signs.
+
+\verbatim
+cat <<END > /mychroot/etc/paludis/bashrc
+export CFLAGS="-O2 -march=pentium4 -fomit-frame-pointer"
+export CXXFLAGS="\${CFLAGS}"
+export CHOST="i686-pc-linux-gnu"
+export MAKEOPTS="-j2"
+export EBEEP_IGNORE="yes"
+export EPAUSE_IGNORE="yes"
+
+case "${PN}" in
+
+    python)
+        export SKIP_FUNCTIONS=test
+        export SANDBOX_PREDICT=/
+        ;;
+
+    automake|glibc|e2fsprogs|neon|gettext)
+        export SKIP_FUNCTIONS=test
+        ;;
+
+esac
+
+END
+\endverbatim
+
+Set up your repository files. Do not tinker with the VDB location, it
+<b>must</b> go in <code>${ROOT}/var/db/pkg</code>. Here we'll avoid using
+<code>/usr/portage</code> for the main tree because sticking data that gets
+changed on <code>/usr</code> is silly. We use the <code>${ROOT}</code> variable,
+which is set magically, to make the config work both in and outside of a
+chroot (this is one of the reasons we have the weird-looking specpath
+thing):
+
+\verbatim
+cat <<END > /mychroot/etc/paludis/repositories/gentoo.conf
+location = \${ROOT}/var/paludis/repositories/gentoo/
+sync = rsync://rsync.europe.gentoo.org/gentoo-portage/
+profile = \${ROOT}/var/paludis/repositories/gentoo/profiles/default-linux/x86/2006.0
+format = portage
+END
+
+cat <<END > /mychroot/etc/paludis/repositories/installed.conf
+location = \${ROOT}/var/db/pkg/
+format = vdb
+END
+
+cat <<END > /mychroot/etc/paludis/repositories/paludis-overlay.conf
+location = \${ROOT}/var/paludis/repositories/paludis-overlay/
+sync = svn://svn.berlios.de/paludis/overlay
+profile = \${ROOT}/var/paludis/repositories/gentoo/profiles/default-linux/x86/2006.0
+eclassdir = \${ROOT}/var/paludis/repositories/gentoo/eclass
+distdir = \${ROOT}/var/paludis/repositories/gentoo/distfiles
+cache = /var/empty
+format = portage
+importance = 10
+END
+\endverbatim
+
+\section BootstrapHowtoSync Initial Sync
+
+Now check that the config looks ok, and sync:
+
+\verbatim
+paludis --config-suffix bootstrap --list-repositories
+sudo paludis --config-suffix bootstrap --sync
+\endverbatim
+
+If you have problems, try adding <code>--log-level debug</code>. This may or may
+not give helpful information... This applies at all stages.
+
+The initial sync will be slow. You can cheat and copy an existing Portage tree
+checkout into <code>/mychroot/var/paludis/repositories/gentoo/</code>, but
+remember to preserve mtimes and permissions if you do. Note that there's no
+hideously painful 'Updating the Portage cache...' to go through. Paludis will
+use the metadata cache, if available, but does not use the dep cache.
+
+\section BootstrapInstalling Installing Things
+
+Now install baselayout and then system. We install baselayout manually first
+because it's easier than creating a bunch of directories by hand.
+
+Note that there're a whole load of circular dependencies in system
+(ncurses <-> gpm, patch <-> patch, gcc <-> glibc for example), so you'll
+almost certainly need --dl-drop-circular at this stage.
+
+\verbatim
+paludis --config-suffix bootstrap --install --pretend --dl-drop-all sys-apps/baselayout
+sudo paludis --config-suffix bootstrap --install --dl-drop-all sys-apps/baselayout
+
+paludis --config-suffix bootstrap --install --pretend --dl-drop-circular system
+sudo paludis --config-suffix bootstrap --install --dl-drop-circular system
+\endverbatim
+
+Note that system will pull in Portage. That's a profiles thing that's
+unavoidable for now. It won't pull in Paludis, so we do that manually.
+
+\note It seems apr and apr-util are rather picky about compiling into ROOT
+unless an identical version is installed onto / .
+
+\verbatim
+paludis --config-suffix bootstrap --install --pretend sys-apps/paludis
+sudo paludis --config-suffix bootstrap --install sys-apps/paludis
+\endverbatim
+
+\section BootstrapHowtoChroot Chrooting
+
+And that should (but probably won't) give you a usable chroot:
+
+\verbatim
+sudo cp /etc/resolv.conf /mychroot/etc/
+sudo chroot /mychroot
+reset
+export HOME=/root
+cd
+cp /etc/skel/.bashrc .
+. .bashrc
+ln -sf /usr/share/zoneinfo/Europe/London /etc/localtime
+mount -tproc none /proc
+mount -tsysfs none /sys
+udevstart
+mount -tdevpts none /dev/pts
+eselect env update
+source /etc/profile
+( . /etc/paludis/bashrc ; export REAL_CHOST=$CHOST ; gcc-config 1 )
+eselect env update
+source /etc/profile
+paludis --uninstall sys-apps/portage
+paludis --install app-editors/vim
+paludis --uninstall app-editors/nano
+\endverbatim
+
+If you're especially crazy you can tar up your chroot and use it like a stage 3
+when installing a system. This has worked at least once for one person, but
+note that there was a full moon at the time.

+
+/**
+\page CodingStandards Coding Standards
+
+These are rough guidelines. You should stick to these unless there's a good
+reason to do otherwise. There are lots more standards that aren't documented
+here yet -- ask for clarification as necessary.
+
+\section CodingStandardsCopyrights Copyrights and Licence
+
+Paludis is licenced under the GPLv2. Any contributions must use this licence.
+You should copy the standard licence header from another source file when
+creating new source files.
+
+Copyright is handled on a per-file basis. If you are the primary author of
+a file, you should list yourself as the copyright holder. If you make a
+substantial contribution to a source file (for example, one or more
+non-trivial classes, functions or methods), you should add yourself as a
+copyright holder on that file. You should <em>not</em> add to the copyright for
+small changes or bug fixes.
+
+Copyright years are per contributor. See, for example, paludis/fs_entry.hh for
+a file that has multiple copyright holders with different years.
+
+Substantial contributors should also list themselves in the AUTHORS file.
+
+\section CodingStandardsIndentingAndSpacing Indenting and Spacing
+
+Indents are four spaces. There are no tabs anywhere. Braces go on a line of
+their own, and may be omitted if the clarity of the code isn't affected. Make
+sure you don't include trailing whitespace.
+
+Function calls have no space before or after the parentheses. Most operators
+and built-in functions have spaces before the opening parenthesis but not
+inside. The ! operator has a space after it.
+
+For example::
+\code
+if (some_function("moo", 2))
+    do_stuff("moo");
+else
+{
+    // this needs some explanation
+    while (end != do_other_stuff(foo) || ! foo)
+        ++foo;
+}
+\endcode
+
+\section CodingStandardsSwitches Switches
+
+You'll sometimes see code like this:
+
+\code
+do
+{
+    switch (my_enum)
+    {
+        case e_one:
+            // ...
+            continue;
+
+        case e_two:
+            // ...
+            continue;
+    }
+
+    throw InternalError(PALUDIS_HERE, "Unexpected value for my_enum");
+} while (false);
+\endcode
+
+The reason for using this rather than a <code>default:</code> label is that the
+compiler will (or at least the compiler we use will) generate a warning if
+someone later goes and adds <code>e_three</code>, and we haven't updated our
+switch to recognise it.
+
+\section CodingStandardsComments Comments
+
+All public and protected interfaces and classes should be documented in the
+header files via Doxygen. Implementations should be documented appropriately --
+explain complicated or unobvious parts and anything that can easily be broken
+by other people. Don't bother with comments on obvious things.
+
+\section CodingStandardsNaming Naming
+
+Types are named in <code>MixedCaseNoUnderscores</code>.
+
+Variables and functions are named in <code>lower_case_with_underscores</code>.
+
+Private member variables that aren't going to end up being used anywhere
+external are <code>_prefixed_with_underscore</code>.
+
+Template values are <code>suffixed_with_underscore_</code>, and template
+typenames are <code>SuffixedAsWell_</code> (and use <code>typename</code> rather
+than <code>class</code>, \ref EffCpp item 42).
+
+The files for <code>SomeClass</code> (and any small related utilities) would be
+<code>some_class.hh</code> and <code>some_class.cc</code>. We are somewhat
+inconsistent when it comes to what warrants its own file -- originally it was
+pretty much one class per file, but then compiles started taking too long so
+it's now more like one class plus related utilities and exceptions per file.
+
+Macros are <code>PALUDIS_UPPER_CASE</code>, but they're evil (\ref TCppPL
+section 7.8, \ref EffCpp item 2) so don't use them.
+
+Very short names for loop indices and the like are fine, but prefer longer,
+self-documenting names for proper variables. For loop iterator pairs, the
+usual style is:
+
+\code
+for (MyType::Iterator i(my_container.begin()), i_end(my_container.end()) ;
+        i != i_end ; ++i)
+{
+    // ...
+}
+\endcode
+
+If there's a convenient standard library algorithm available, use that
+instead of a manual loop (\ref EffSTL item 43).
+
+\section CodingStandardsPointers Pointers and References
+
+Try to avoid returning raw pointer types from raw interfaces, especially if the
+programmer is expected to deallocate them manually. Make liberal use of
+<code>paludis::CountedPtr</code> instead -- it's low overhead and a lot less
+prone to subtle screwups. See \ref EffCpp item 18.
+
+Pass object parameters by const reference rather than pointer to const unless
+you're prepared to accept a zero pointer. Avoid pass by value except for small
+integral types. See \ref EffCpp item 20.
+
+\section CodingStandardsNamespaces Namespaces
+
+Everything under <code>paludis/</code> should be inside namespace
+<code>paludis</code>. Sometimes sub-namespaces are used where they look useful.
+
+\section CodingStandardsIncludeGuards Include Guards
+
+Include guards are <code>\#define PALUDIS_GUARD_FILE_NAME_HH 1</code>.
+
+\section CodingStandardsStandardLibrary Standard Library
+
+Never use <code>using namespace std</code>. It can bring arbitrary weirdness
+into the current namespace. It's ok to selectively introduce things from std
+where they're used a lot. See \ref TCppPL section 8.2.9.1.
+
+Make use of the standard library where suitable. It has fewer bugs than
+code you write yourself, and it may be doing clever optimisations behind
+the scenes.
+
+Remember the container member functions. Many containers have template
+constructors that take iterator pairs. Many containers have assign and
+swap methods. Use these over <code>std::copy</code>. See \ref EffSTL item
+25.
+
+Don't use <code>vector&lt;bool&gt;</code>. It's just not worth it. See
+\ref EffSTL item 18.
+
+Although some compilers will let you get away with <code>std::make_pair("foo",
+"bar")</code>, some won't. Strictly speaking this violates the standard.
+Use <code>std::make_pair(std::string("foo"), std::string("bar"))</code> instead.
+
+\section CodingStandardsCasts Casts
+
+<code>dynamic_cast</code> is banned. It's slow (\ref EffCpp item 27) and a sign
+that you should be using one of visitors (\ref GoF Visitor), multiple dispatch
+(\ref MCppD chapter 11) or capability queries via a <code>get_interface</code>
+type method (for example, as described in \ref GoF Composite -- Implementation
+item 4) instead.
+
+<code>reinterpret_cast</code> is probably banned as well, unless we end up
+having to talk to some weirdly broken C libraries.
+
+There are very few legitimate uses for <code>const_cast</code>. It
+<em>might</em> be ok to use it as described in \ref EffCpp item 3. It
+<em>might</em> be ok to use it to talk to C libraries.
+
+There's nothing wrong with making appropriate use of <code>static_cast</code>.
+
+Old C style <code>(Type) variable</code> casts are banned. Function style casts
+(that is, <code>Type(value)</code>) should only be used when calling an explicit
+constructor to pass an object to a function. See \ref EffCpp item 27.

+\section overview Overview
+
+This is the documentation for Paludis, the other package manager. It is available as part of Paludis via <code>make doxygen</code>, or on the web at <a href="http://paludis.berlios.de/">the Paludis project page</a>.
+
+\section userdocs For End Users
+
+You shouldn't be touching Paludis at the moment. Paludis will delete all your
+files, then delete everyone else's files, then rape your dog. Go away.
+
+If you're still here, read \link BootstrapHowto the Bootstrap HOWTO \endlink for
+how to break your system or possibly set up a chroot. You may also like to read
+about \link PortageDifferences some of the differences between Paludis and
+Portage\endlink.
+
+We have a <a href="https://developer.berlios.de/bugs/?group_id=6360">bug
+tracker</a> and some
+<a href="https://developer.berlios.de/mail/?group_id=6360">mailing lists</a>, but
+you shouldn't try to use these until after you've discussed your problem in our
+IRC channel. Read the howto for more details.
+
+\section developerdocs For Developers
+
+Start by getting a
+<a href="https://developer.berlios.de/svn/?group_id=6360">Subversion
+checkout</a>, and reading the \link PortageDifferences Paludis and Portage
+differences \endlink document.
+
+It's best to start by skimming over the main program to get a feel for how
+everything fits together. Useful files:
+
+- src/paludis.cc The main program.
+- src/query.cc The --query action handler.
+- src/install.cc The --install action handler.
+- src/applets.cc Various small action handlers.
+- src/list.cc The --list action handlers
+
+After that, the following classes are good places to begin:
+
+- paludis::DefaultEnvironment provides a representation of the default
+  operating environment.
+- paludis::PackageDatabase provides routines for querying packages. An
+  instance can be obtained via paludis::DefaultEnvironment.
+- paludis::DepList can be used for making dependency lists.
+- paludis::Repository is subclassed to do querying, installing,
+  uninstalling, syncing and the like.
+
+The <a href="modules.html">Modules</a> link in the header bar will probably
+be of more use than any of the full class lists.
+
+You should also read \link CodingStandards the Coding Standards \endlink
+before tinkering.

+/**
+\page PortageDifferences How Paludis and Portage Differ
+
+This is not a complete list. It's not even vaguely near complete. Rather, it's
+a collection of lists of things of interest that are intentionally different
+between Paludis and its predecessor, Portage.
+
+\section PortageDifferencesEndUser For the End User
+
+Paludis isn't aimed at end users. Having said that, the following features
+would be relevant if it were:
+
+- A whole different configuration system, making it far easier to maintain
+  multiple systems, some in chroots, with entirely separate configuration
+  files.
+
+- Performance. Paludis is fast.
+
+- Low dependency bloat. No Python, no big external crypto libraries.
+
+- Security integration.
+
+- Multiple repository support, replacing Portage's highly limited overlays.
+
+- Simple per-(category, package, version, anything else) environment variable
+  setting (e.g. CFLAGS).
+
+- Licence filtering.
+
+- Hook scripts, for running code after a certain action occurs.
+
+- Wrappers for econf, emake, wget etc to allow user defined command bindings
+  (nice, ionice, taskset etc).
+
+\section PortageDifferencesEbuildDeveloper For the Ebuild Developer
+
+As well as the end user advantages, ebuild authors will benefit from:
+
+- :slot dependencies
+
+- ::repository dependencies
+
+- [use] dependencies
+
+- Circular dependency detection
+
+- Per package use masking, and from this per package use combination
+  restrictions.
+
+- Default deep dependency resolution.
+
+- Support for -scm versions.
+
+- Multiple inheritance for profiles.
+
+- Ability to install hook scripts.
+
+\section PortageDifferencesProgrammer For the Programmer
+
+- Proper library / interface separation.
+
+- Reasonable internals documentation, via Doxygen.
+
+- Consistent interfaces for different repository types.
+
+- Modularity where it matters.
+
+- Test suites, to detect the impact of changes.
