=head1 NAME
splitpatch - split a patch up into files or hunks
=head1 SYNOPSIS
splitpatch [options]
=head1 DESCRIPTION
Divide a patch or diff file into pieces. The split can made by file
or by hunk basis. This makes is possible to separate changes that
might not be desirable, or assemble a patch into more coherent set
of changes.
The hunk option makes it possible to compare similar patches on a
hunk-by-hunk basis using a tool like interdiff(1) from the patchutils package.
=head1 OPTIONS
=over 4
=item B<-H, --hunk, --hunks>
Split patch by hunks instead of the default: by file.
=item B<-h, --help>
Display help and exit
=item B<-V, --version>
Output version information and exit.
=back
=head1 EXAMPLES
Have you ever been working on code, gone off on a side tangent and
then realized you don't have a patch for the original issue you
set out to address? When you run C<diff -u> or some other diff command,
you discover that you have made multiple sets of changes; some
you want to submit, others you don't. What you really want to do is
break those changes apart and apply only the ones you want. This is
where splitpatch comes into play, breaking up the patch by source file:
splitpatch changes.patch
Or to split the patch file into individual hunks which can later be
applied using the patch(1) command:
splitpatch --hunks changes.patch
=head1 ENVIRONMENT
None.
=head1 FILES
The B<--hunk> option writes sequentially numbered files in the current
directory named for the source file to be patched followed by the
sequence number: C<*-NNN.patch>.
Otherwise, the split patch files are named by the source file being
patched.
=head1 STANDARDS
None.
