#!/usr/bin/env perl
=head1 NAME
import_content.pl - import content from a file into a MojoMojo page
=head1 SYNOPSIS
script/util/import_content.pl /path/to/page page.markdown
Since this operation is undoable, the script will prompt you to confirm that
you really want to replace the contents of the last version of /path/to/page
with what's in F<page.markdown>.
=head1 DESCRIPTION
Replace the contents of the last version of a page with the content from a
file. Useful if you want to fix a typo in a page without bumping the version
and creating yet another revision in the database. Of course, can be used for
evil, but then so could be a series of SQL commands.
