=head1 NAME

rpws - Implements multiple workspaces in ratpoison

=head1 SYNOPSIS

 rpws init n [-k] [-a]  - setup rpws with n workspaces.
                            -a sets up command aliases;
                            -k sets up key bindings and aliases.
 rpws dump <fname>      - dumps the current layout to <fname>
 rpws restore <fname>   - restores rpws workspaces from <fname>
 rpws current           - print the current workspace
 rpws help              - this documentation
 rpws n                 - switch to this workspace


=head1 DESCRIPTION

 B<rpws> implements multiple workspaces in ratpoison by making calls
 to fdump, freestore.  It was adapted from rpws which comes with
 ratpoison in the contrib directory.

=head1 USAGE

Add the following line in ~/.ratpoisonrc

     exec /path/to/rpws init 6 -k

This creates 6 aliases rpws1, rpws2, etc. It also binds the keys M-F1,
M-F2, etc to each rpwsN alias. Moreover, rpwsn (Next) and rpwsp (Prev) are
created, and C-M-{Right,Left} are bound to rpws{n,p}. Aliases rpwsm1, rpwsm2,
etc. and rpwsm{n,p} are used to move the focused window to another workspace.

Full list of keybindings created are:

    M-F$i           Goto workspace $i
    C-M-Right       Goto Next workspace
    C-M-Left        Goto Prev workspace
    C-M-S-F$i       Move window to workspace $i
    C-M-greater     Move current window to next workspace
    C-M-less        Move current window to prev workspace

=head1 FILES

 rpws requires use of a lockfile.  It defaults to using
/tmp/rpws.<UID>.lock but this can be changed by setting the
environment variable RPWS_LOCKFILE to your desired lockfile.
