=head1 NAME
    s2t or ts (One is symlinked to the other.)
 
=head1 SYNOPSIS
 
s2t [file] B<or> ts  [file]
 
=head1 DESCRIPTION
 
A command-line script to work with Perl data structures created by Sto
+rable.pm
 
This file should be called B<s2t> and a file called B<ts> should be sy
+mlinked
to it like so:
 
    ln -s s2t ts
 
The script consists of two subroutines, one of which is called dependi
+ng on the
scriptname.
 
=head1 s2t (Storable 2 Text)
 
Opens a file created by Storable::lock_store and dumps the data struct
+ure to an
ascii file for viewing/editing.  The extension '.txt' is appended to t
+he end of
the new file to indicate that it's editable. (Storable.pm creates bina
+ry files
which load quickly, but aren't editable.)
 
When you've finished editing the .txt file, you should run it through 
+perl to
re-create the original Storable file.  There are a couple of different
+ ways to
do this:
 
=over 4
 
=item * B<From Vi>
 
 :%!perl
 
=item * B<From the command line>
 
 perl foobar.txt
 
=back
 
=head1 ts (Touch Storable)
 
    Creates a file with Storable::lock_store that contains an EMPTY ha
+sh reference.
 
    Some scripts try to open files created by Storable::lock_store. Th
+is creates those files in the right format.
