+=head1 SYNOPSIS
+
+ webidx [-x FILE [-x FILE2 [...]]] [--xP PATTERN [--xP PATTERN2 [...]]] [-o ORIGIN] [-z] [DIRECTORY] [DBFILE]
+
+This will cause all HTML files in C<DIRECTORY> to be indexed, and the resulting database written to C<DBFILE>. The supported options are:
+
+=over
+
+=item * C<-x FILE> specifies a file to be excluded. May be specified multiple times.
+
+=item * C<--xP PATTERN> specifies a pattern of folders and files to be excluded. May be specified multiple times.
+
+=item * C<-o ORIGIN> specifies a base URL which will be prepended to the filenames (once C<DIRECTORY> has been removed).
+
+=item C<-z> specifies that the database file should be compressed once generated. If specified, the database will be at C<DBFILE.gz>.
+
+=item * C<DIRECTORY> is the directory to be indexed, defaults to the current working directory.
+
+=item * C<DBFILE> is the location where the database should be written. if not specified, defaults to C<DIRECTORY/index.db>.
