xbps - xtraeme's build package system.

It is a simple build package system that uses Xstow to allow packages
to be available at a master directory.

xbps uses proplib, a property container object library and it's almost the
same one available for NetBSD. Be sure to have it installed before using
xbps. You can get it at:

 HOW TO USE IT
------------------------------------------------------------------------------

Before using xbps, some required utilities need to be built and installed into
the utils/ directory. You can do this by issuing a "make" command in the
top level directory.

Once you download it, you should edit the configuration file located at the
xbps directory. By default it uses the xbps directory in your $HOME.

If XBPS_CONFIG_FILE is not set or specified from the command line with the
-c flag, it will first try to use the default location at
/usr/local/etc/xbps.conf, and as last resort in current directory.

Once that you read the "xbps.conf" file and configured it, you can start
installing packages by using the command:

	$ xbps.sh install glib

While installing your first package, if xbps couldn't find the Xstow program
specified at the configuration file with XBPS_XSTOW_CMD, the Xstow package
will be installed and "stowned".

If the package is properly installed, it will be "stowned" automatically.
``stowned´´ means that this package is available in the master directory,
on which xpbs has copied all files from DESTDIR/<pkgname>.

To remove a currently installed (and stowned) package, you can use:

	$ xbps.sh remove glib

Please note that when you remove it, the package will also be removed
from XBPS_DESTDIR and previously "unstowned".

Summary, to stow an already installed package (into XBPS_DESTDIR/<pkgname>):

	$ xbps.sh stow glib

and to unstow an already installed (stowned) package:

	$ xbps.sh unstow glib

You can also print some stuff about any template, e.g:

	$ xbps.sh info glib

To list installed (stowned) packages, use this:

	$ xbps.sh list

To only extract the distfiles, without configuring/building/installing:

	$ xbps.sh extract foo

To not remove the build directory after successful installation:

	$ xbps.sh -C install blah

To only fetch the distfile:

	$ xbps.sh fetch blah

To only install the package, _without_ stowning it into the master directory:

	$ xbps.sh install-destdir blob

To list files installed by a package, note that package must be installed
into destination directory first and you must specify package name plus
version, i.e: vim-7.2:

	$ xbps.sh listfiles blob-2.4

That's all for now folks. I hope you find it useful, as I do.

 PERFORMANCE
------------------------------------------------------------------------------

xbps is really fast, trust me. That was one of my reasons to make my own
pkgsrc/ports alike system.

If you want benchmarks, here is one: building libX11 and all its dependencies
required (not included building xstow) with xbps:

	251.20s real   121.36s user    53.94s system

versus pkgsrc (make install clean clean-depends and digest previously
installed):

	450.41s real   167.58s user    97.31s system

That's more or less 40% faster! that's the price you pay for having those
wrappers in pkgsrc that aren't very useful on NetBSD :-)
