    <para><application>CVS</application> is the Concurrent Versions System.
    This is a version control system useful for projects using a central

    These instructions install the client used to manipulate the repository,
    creation of a repository is covered at <xref linkend="cvsserver"/>.</para>

    <title>Installation of CVS</title>

    <para>By default <application>CVS</application> is statically linked
    against the <application>Zlib</application> library included in its source
    tree. This makes it exposed to possible security vulnerabilities in that
    library. If you want to modify <application>CVS</application> to use the
    system shared <application>Zlib</application> library, apply the following
    patch:</para>

<screen><userinput>patch -Np1 -i ../cvs-&cvs-version;-zlib-1.patch</userinput></screen>

    <para>Now fix some conflicts with newer libraries and programs:</para>

<screen><userinput>sed -i -e 's/getline /get_line /' lib/getline.{c,h} &amp;&amp;
sed -i -e 's/^@sp$/&amp; 1/'          doc/cvs.texinfo &amp;&amp;
touch doc/*.pdf</userinput></screen>

    <para>Install <application>CVS</application> by running
    the following commands:</para>

<screen><userinput>./configure --prefix=/usr --docdir=/usr/share/doc/cvs-&cvs-version; &amp;&amp;
make</userinput></screen>

    <para>If you wish to create HTML or text docs from the
    documentation source files, issue the following command:</para>

<screen><userinput>make -C doc html txt</userinput></screen>

    <para>To test the results, issue: <command>make check</command>. This will
    take quite a while. If you don't have <command>rsh</command> configured for
    access to the host you are building on (or you didn't pass the
    <option>--with-rsh=</option> parameter to the <command>configure</command>
    script, some tests may fail. If you passed the
    <option>--with-rsh=ssh</option> parameter to enable <command>ssh</command>
    as the default remote shell program, you'll need to issue the following
    command so that the tests will complete without any failures:</para>

<screen><userinput>sed -e 's/rsh};/ssh};/' \
    -e 's/g=rw,o=r$/g=r,o=r/' \
    -i src/sanity.sh</userinput></screen>

    <para>Now, as the <systemitem class="username">root</systemitem> user:</para>

<screen role='root'><userinput>make install &amp;&amp;
make -C doc install-pdf &amp;&amp;
install -v -m644 FAQ README /usr/share/doc/cvs-&cvs-version;</userinput></screen>

    <para>If you created any additional documentation, install it by issuing
    the following commands as the
    <systemitem class="username">root</systemitem> user:</para>

<screen role='root'><userinput>install -v -m644 doc/*.txt /usr/share/doc/cvs-&cvs-version;                   &amp;&amp;
install -v -m755 -d        /usr/share/doc/cvs-&cvs-version;/html/cvs{,client} &amp;&amp;
install -v -m644 doc/cvs.html/* \
                           /usr/share/doc/cvs-&cvs-version;/html/cvs          &amp;&amp;
install -v -m644 doc/cvsclient.html/* \
                           /usr/share/doc/cvs-&cvs-version;/html/cvsclient</userinput></screen>

      <para><filename>~/.cvsrc</filename> is the main

      This file is used by users to specify defaults for different
      <command>cvs</command> commands. For example, to make all
      <command>cvs diff</command> commands run with <option>-u</option>, a user
      would add <option>diff -u</option> to their <filename>.cvsrc</filename>
      file.</para>

      <para><filename>~/.cvswrappers</filename> specifies wrappers to be used in
      addition to those specified in the <filename>CVSROOT/cvswrappers</filename>
      file in the repository.</para>

      <para><filename>~/.cvspass</filename> contains passwords used to complete
      logins to servers.</para>
