+The <command>cygcheck</command> program is a diagnostic utility for
+dealing with Cygwin programs. If you are familiar with
+<command>dpkg</command> or <command>rpm</command>,
+<command>cygcheck</command> is similar in many ways. (The major difference
+is that <command>setup.exe</command> handles installing and uninstalling
+packages; see <xref linkend="internet-setup"> for more information.)

+<para>
+The <literal>-c</literal> option checks the version and status of 
+installed Cygwin packages. If you specify one or more package names,
+<command>cygcheck</command> will limit its output to those packages,
+or with no arguments it lists all packages. A package will be marked
+<literal>Incomplete</literal> if files originally installed are no longer
+present. The best thing to do in that situation is reinstall the package
+with <command>setup.exe</command>. To see which files are missing, use the
+<literal>-v</literal> option. If you do not need to know the status
+of each package and want <command>cygcheck</command> to run faster, add the
+<literal>-d</literal> option and <command>cygcheck</command> will only
+output the name and version for each package.
