=head1 NAME
make-zsh-urls -- create F<~/.zsh/urls> hierarchy
=head1 SYNOPSIS
% make-zsh-urls [B<OPTION>] ...
=head1 DESCRIPTION
make-zsh-urls creates a hierarchy of files and directories under
F<~/.zsh/urls> for use by the _urls completion function in the new
completion system of zsh 3.1.6 and higher.
It needs the B<URI::Bookmarks> suite of modules to run, which are
available from CPAN, the Comprehensive Perl Archive Network.
See B<http://www.perl.com/cpan> or L<CPAN> for more information.
The following options are available:
B<--output-dir>, B<-o> Specify the output directory for the
hierarchy. Defaults to F<~/.zsh/urls>.
B<--input-file>, B<-i> Specify the input bookmarks file.
Defaults to F<~/.netscape/bookmarks.html>.
B<--root-node>, B<-r> Specify which folder contains the
bookmarks which the hierarchy will be
created from. Defaults to the root
of the bookmark collection tree.
