=head1 NAME
narada-diff - prepare patch from previous version to current
=head1 VERSION
This document describes narada-diff version 1.3.6
=head1 USAGE
narada-diff
=head1 DESCRIPTION
Script must be executed only from "project root directory".
When executed, script will delete C<var/patch/CURRENT.*> files, then
detect all changes between previous and current project versions and
generate from 0 (if there are no changes) to 4 files with these names:
var/patch/CURRENT.10.sh
var/patch/CURRENT.20.patch
var/patch/CURRENT.30.tgz
var/patch/CURRENT.40.sh
You should review these files - if something is wrong, then make changes
to project and run C<narada-diff> again until you'll be happy.
Next you can manually modify these files. If you need to add some commands
to .sh files - it's better to put them into C<var/patch/PENDING.*.sh>
instead of modifying these files. But if you need to remove some changes
from these files to avoid including them into next update - it's ok.
Now, run C<narada-release> to release next update with all changes from
current C<var/patch/CURRENT.*> and C<var/patch/PENDING.*> files.
When detecting changes it take in account C<config/patch/exclude> plus
handle files in C<config/> in special way: only added and removed files
processed, changed files ignored.
