-The git version control system allows you to keep up-to-date with the
-latest changes to the development version of ERC.  It also allows you
-to contribute changes (via commits, if you are have developer access to
-the repository, or via patches, otherwise).  If you would like to
-contribute to ERC development, it is highly recommended that you use
-git.
-
-If you are new to git, you might find this tutorial helpful:
-@uref{http://www.kernel.org/pub/software/scm/git/docs/gittutorial.html}.
-
-Downloading ERC with git and staying up-to-date involves the following
-steps.
-
-@enumerate
-@item Install git.
-
-@itemize @bullet
-@item Debian and Ubuntu: @kbd{apt-get install git-core}.
-@item Windows: @uref{http://git.or.cz/gitwiki/WindowsInstall}.
-@item Other operating systems: download, compile, and install the source
-from @uref{http://www.kernel.org/pub/software/scm/git/}, or find a git
-package for your operating system.
-@end itemize
-
-@item Download the ERC development branch.
-
-If you have developer access to ERC, do:
-
-@example
-git clone ssh://loginname@@git.sv.gnu.org/srv/git/erc.git
-@end example
-
-otherwise, do:
-
-@example
-git clone git://git.sv.gnu.org/erc.git
-@end example
-
-If you are behind a restrictive firewall, and do not have developer
-access, then do the following instead:
-
-@example
-git clone http://git.sv.gnu.org/r/erc.git
-@end example
-
-@item List upstream changes that are missing from your local copy.
-Do this whenever you want to see whether new changes have been committed
-to ERC.  If you wish, you may skip this step and proceed directly to
-the ``update'' step.
-
-@example
-# Change to the source directory you are interested in.
-cd erc
-
-# Fetch new changes from the repository, but don't apply them yet
-git fetch origin
-
-# Display log messages for the new changes
-git log HEAD..origin
-@end example
-
-``origin'' is git's name for the location where you originally got ERC
-from.  You can change this location at any time by editing the
-@file{.git/config} file in the directory where the ERC source was
-placed.
-
-@cindex updating ERC with git
-@item Update to the latest version by pulling in any missing changes.

-@node Installation
-@chapter Installation
-
-ERC may be compiled and installed on your machine.
-
-This section may be skipped if you are using the version of ERC that
-comes with Emacs.
-
-@subsubheading Compilation
-
-This is an optional step, since Emacs Lisp source code does not
-necessarily have to be byte-compiled.  It will yield a speed increase,
-though.
-
-A working copy of Emacs or XEmacs is needed in order to compile ERC.  By
-default, the program that is installed with the name @command{emacs}
-will be used.
-
-If you want to use the @command{xemacs} binary to perform the
-compilation, you would need to edit @file{Makefile} in the top-level
-directory as follows.  You can put either a full path to an Emacs or
-XEmacs binary or just the command name, as long as it is in the
-@env{PATH}.
-
-@example
-EMACS    = xemacs
-SITEFLAG = -no-site-file
-@end example
-
-Running @code{make} should compile the ERC source files in the
-@file{lisp} directory.
-
-@subsubheading Installation
-
-ERC may be installed into your file hierarchy by doing the following.
-
-Edit the @file{Makefile} file so that @env{ELISPDIR} points to where you
-want the source and compiled ERC files to be installed and
-@env{INFODIR} indicates where to put the ERC manual.  Of course, you
-will want to edit @env{EMACS} and @env{SITEFLAG} as shown in the
-Compilation section if you are using XEmacs.
-
-If you are installing ERC on a Debian system, you might want to change
-the value of @env{INSTALLINFO} as specified in @file{Makefile}.
-
-Run @code{make} as a normal user.
-
-Run @code{make install} as the root user if you have chosen installation
-locations that require this.
