   <title>Running a <productname>CVSup</productname> Client</title>

   <para>
    Verify that
    <application>cvsup</application> is in your path; on most systems
    you can do this by typing

<programlisting>
which cvsup
</programlisting>

    Then, simply run
    <application>cvsup</application> using:

<programlisting>
cvsup -L 2 <replaceable class="parameter">postgres.cvsup</replaceable>
</programlisting>

    where <option>-L 2</option> enables some status messages so you
    can monitor the progress of the update,
    and <replaceable class="parameter">postgres.cvsup</replaceable> is
    the path and name you have given to your
    <productname>CVSup</productname> configuration file.
   </para>

   <para>
    Here is a <productname>CVSup</productname> configuration file
    modified for a specific installation, and which maintains a full
    local <productname>CVS</productname> repository:

<programlisting>
# This file represents the standard CVSup distribution file
# for the <productname>PostgreSQL</> ORDBMS project
# Modified by [e-mail] 1997-08-28
# - Point to my local snapshot source tree
# - Pull the full CVS repository, not just the latest snapshot
#
# Defaults that apply to all the collections
*default host=cvsup.postgresql.org
*default compress
*default release=cvs
*default delete use-rel-suffix
# enable the following line to get the latest snapshot
#*default tag=.
# enable the following line to get whatever was specified above or by default
# at the date specified below
#*default date=97.08.29.00.00.00

# base directory where CVSup will store its 'bookmarks' file(s)
# will create subdirectory sup/
#*default base=/opt/postgres # /usr/local/pgsql
*default base=/home/cvs

# prefix directory where CVSup will store the actual distribution(s)
*default prefix=/home/cvs

# complete distribution, including all below
pgsql

# individual distributions vs 'the whole thing'
# pgsql-doc
# pgsql-perl5
# pgsql-src
</programlisting>
   </para>

   <para>
    If you specify <option>repository</> instead of <option>pgsql</>
    in the above setup, you will get a complete copy of the entire
    repository at cvsup.postgresql.org, including its
    <filename>CVSROOT</filename> directory. If you do that, you will
    probably want to exclude those files in that directory that you
    want to modify locally, using a refuse file. For example, for the
    above setup you might put this in
    <filename>/home/cvs/sup/repository/refuse</>:
<programlisting>
CVSROOT/config*
CVSROOT/commitinfo*
CVSROOT/loginfo*
</programlisting>
    See the <productname>CVSup</> manual pages for how to use refuse files.
   </para>

   <para>
    The following is a suggested <productname>CVSup</productname> config file from
    the <productname>PostgreSQL</>
    <ulink url="ftp://ftp.postgresql.org/pub/CVSup/README.cvsup">
    ftp site</ulink>
    which will fetch the current snapshot only:

<programlisting>

   <title>Installing <productname>CVSup</productname></title>

   <para>
    <productname>CVSup</productname> is available as source, pre-built
    binaries, or Linux RPMs. It is far easier to use a binary than to
    build from source, primarily because the very capable, but
    voluminous, Modula-3 compiler is required for the build.
   </para>

   <procedure>
    <title><productname>CVSup</productname> Installation from Binaries</title>

    <para>
     You can use pre-built binaries
     if you have a platform for which binaries
     are posted on the <productname>PostgreSQL</productname>
     <ulink url="ftp://ftp.postgresql.org/pub">
     ftp site</ulink>
     or if you are running FreeBSD, for which
     <productname>CVSup</productname> is available as a port.

     <note>
      <para>
       <productname>CVSup</productname> was originally developed as a
       tool for distributing the <productname>FreeBSD</productname>
       source tree. It is available as a <quote>port</quote>, and for those running
       FreeBSD, if this is not sufficient to tell how to obtain and
       install it then please contribute a procedure here.
      </para>
     </note>
    </para>

    <para>
     At the time of writing, binaries are available for
     Alpha/Tru64, ix86/xBSD,
     HPPA/HP-UX 10.20, MIPS/IRIX,
     ix86/linux-libc5, ix86/linux-glibc,

   <title>Installation from Sources</title>

   <para>
    Installing <productname>CVSup</productname> from sources is not
    entirely trivial, primarily because most systems will need to
    install a Modula-3 compiler first.
    This compiler is available as Linux <productname>RPM</productname>,
    FreeBSD package, or source code.

    <note>
     <para>
      A clean-source installation of Modula-3 takes roughly 200MB of disk space,
      which shrinks to roughly 50MB of space when the sources are removed.</para>
    </note>
   </para>

   <procedure>
    <title>Linux installation</title>

    <step>
     <para>
      Install Modula-3.
     </para>

     <substeps>
      <step>
       <para>
	Pick up the <productname>Modula-3</productname>
	distribution from <ulink url="http://m3.polymtl.ca/m3">
        Polytechnique Montr閍l</ulink>
	who are actively maintaining the code base originally developed by
	the <ulink url="http://www.research.digital.com/SRC/modula-3/html/home.html">
        DEC Systems Research Center</ulink>.
        The <productname>PM3</productname> <productname>RPM</productname> distribution is roughly
	30MB compressed. At the time of writing, the 1.1.10-1 release
	installed cleanly on RH-5.2, whereas the 1.1.11-1 release is
	apparently built for another release (RH-6.0?) and does not run on RH-5.2.

	<tip>
	 <para>
	  This particular rpm packaging has
	  <emphasis>many</emphasis> <productname>RPM</productname> files,
	  so you will likely want to place them into a separate
	  directory.

      <step>

      Build the cvsup distribution, suppressing the GUI interface
      feature to avoid requiring X11 libraries:

<programlisting>
# make M3FLAGS="-DNOGUI"

      and if you want to build a static binary to move to systems
      that may not have Modula-3 installed, try:

<programlisting>
# make M3FLAGS="-DNOGUI -DSTATIC"
</programlisting>
     </para>
