+This is the GNU mailutils package.
+This document describes the actions needed to build the pre-release
+or CVS version of the package. See end of file for copying conditions.
+
+* Introduction
+
+    This is a *pre-release* version, and not ready for production use
+yet. If you are taking source from CVS, you will need to have libtool,
+automake, and autoconf installed to help contribute. See the chapter
+`Building' for the detailed instructions. The script autogen.sh is
+provided to help autoconfigure mailutils from the cvs src.  After you
+run autogen.sh, there should be a file 'INSTALL' with (generic)
+installation instructions. Package-specific installation instructions
+are set forth in the file README.
+
+    Please, note that the accompanying documentation may be inaccurate
+or incomplete. The ChangeLog file is the authoritative documentation of
+all recent changes.
+
+Report bugs to <bug-mailutils@gnu.org>
+
+* Checking Out the Sources
+
+The following instructions apply if you wish to obtain sources from
+the CVS repository:
+
+To checkout the source tree from CVS issue the following command:
+
+CVS_RSH=ssh \
+ cvs -d :ext:anoncvs@savannah.gnu.org:/cvsroot/mailutils checkout mailutils
+
+Make sure SSHv2 is used.
+
+    This will give you read-only access.  If you think you need write access,
+contact the mailing list.
+
+* Building
+
+    In order to build this you will first need to have right versions
+of autotools and some auxiliary GNU programs. At the time of this
+writing these are: 
+
+  Package   Version (>=)
+  ========  ============
+  automake  1.8.5
+  autoconf  2.59
+  libtool   1.5.8
+  gettext   0.14.1
+  gawk      3.1.3
+
+    You will also need bison (or yacc) and flex. The grammar sources
+were written so that any version of yacc or bison should be able to 
+handle them, however using recent bison is anyway recommended. The lex
+sources could theoretically be compiled with AT&T lex. I have not
+tested this, however, so using flex is higly recommended. I use flex
+2.5.4. 
+  
+    To prepare the package for building run autogen.sh. Then run
+./configure with the desired options (See INSTALL and README for the
+detailed instructions). Finally, run make. Notice that the first make
+of the package should be made in the source directory. Subsequent
+makes can use build directory different from the source one.
+
+* Debugging
+
+    To enable additional debugging information, configure the package
+with --enable-debug option.
+
+    Unless you compile mailutils statically, you will need to run
+following command to debug any utility:
+
+  libtool --mode execute gdb UTILITY-NAME
+
+    Sometimes it is impossible or inconvenient to start a utility from
+the debugger. In this case, use --HANG option, which is supported by
+any of the mailutils programs. The option instructs the program to
+sleep for a given number of seconds (3600 by default) right after
+startup. For example, to debug `mimeview' utility, run
+
+	mimeview --HANG [OTHER-OPTIONS]
+
+Then switch to another terminal, get the PID of the ivoked utility and
+attach to it using gdb: 
+
+	gdb mimeview PID
+
+Once in gdb, issue the following command
+
+	set _argp_hang=0
+
+Now set your breakpoints and proceed as usual.
+
+* Importing gnulib files
+
+    Mailutils imports several source files from gnulib. These go
+mainly to the conventional library libmuaux (directory lib/), but
+several of them are incorporated into the main library libmailutils
+(directory mailbox/). The imported sources are kept in the CVS
+repository to avoid using eventually unstable versions appearing in
+the main gnulib CVS. Once in a time we update the sources. The update
+procedure is quite straightforward: change to the root directory of
+the mailutils tree and run `gnulib-sync' script:
+
+  $ cd mailutils
+  $ scripts/gnulib-sync $HOME/src/gnulib
+
+    The script takes a single argument: name of the directory with the
+copy of gnulib source tree (see http://savannah.gnu.org/projects/gnulib
+for information on how to obtain gnulib sources). After incorporating
+the files, gnulib-sync leaves in the current directory two files named
+gnulib.changelog and gnulib.cvs. The file gnulib.changelog contains
+an entry to be prepended to ChangeLog, the file gnulib.cvs is a shell
+script with the commands necessary to incorporate all the changes into
+CVS. 
+
+    If you need to add more gnulib modules to mailutils, add their
+names to gnulib.modules file, following the instructions in its
+heading comment. Please avoid placing modules in :mailutils section, as
+this may lead to unwanted name clashes when linking user programs with
+libmailutils.
