+=head1 NAME
+
+exigrep - search Exim's main log
+
+=head1 SYNOPSIS
+
+B<exigrep> [options] pattern [log] ...
+
+=head1 DESCRIPTION
+
+The B<exigrep> utility is a Perl script that searches one or more main log
+files for entries that match a given pattern. When it finds a match,
+it extracts all the log entries for the relevant message, not just
+those that match the pattern. Thus, B<exigrep> can extract complete log
+entries for a given message, or all mail for a given user, or for a
+given host, for example.
+
+If no file names are given on the command line, the standard input is read.
+
+For known file extensions indicating compression (F<.gz>, F<.bz2>, F<.xz>, and F<.lzma>)
+a suitable de-compressor is used, if available.
+
+The output is sent through a pager if a terminal is connected to STDOUT. As
+pager are considered: C<$ENV{PAGER}>, C<less>, C<more>.
+
+=head1 OPTIONS
+
+=over
+
+=item B<-l>|B<--literal>
+
+This means 'literal', that is, treat all characters in the
+pattern as standing for themselves. Otherwise the pattern must be a
+Perl regular expression. The pattern match is case-insensitive.
+
+=item B<-t>|B<--queue-time> I<seconds>
+
+Limit the output to messages that spent at least I<seconds> in the
+queue.
+
+=item B<-I>|B<--sensitive>
+
+Do a case sensitive search.
+
+=item B<-v>|B<--invert>
+
+Invert the meaning of the search pattern. That is, print message log
+entries that are not related to that pattern.
+
+=item B<-M>|B<--related>
+
+Search for related messages too.
+
+=item B<--no-pager>
+
+Do not use a pager, even if STDOUT is connected to a terminal.
+
+=item B<-h>|B<--help>
+
+Print a short reference help. For more detailed help try L<exigrep(8)>,
+or C<exigrep -m>.
+
+=item B<-m>|B<--man>
+
+Print this manual page of B<exigrep>.
