Test::Smoke::Patcher - OO interface to help patching the source-tree

use Test::Smoke::Patcher;
my $patcher = Test::Smoke::Patcher->new( single => {
ddir => $build_dir,
pfile => $patch,
popts => '-p1',
v => 1, # 0..2
});
$patcher->patch;
or
my $patcher = Test::Smoke::Patcher->new( multi => {
ddir => $buildir,
pfile => $patch_info,
v => 1, #0..2
});
$patcher->patch;

Okay, you will need a working patch program, which I believe is available for most platforms perl runs on.
There are two ways to initialise the Test::Smoke::Patcher object.
The pfile attribute is a pointer to a single patch. There are four (4) ways to specify that patch.
The scalar holds the complete patch as literal text.
The array holds a list of lines (with newlines) that make up the patch as literal text ($patch = join "", @$array_ref).
You passed an opened filehandle to a file containing the patch.
If none of the above apply, it is assumed you passed a filename. Relative paths are rooted at the builddir (ddir attribute).
The pfile attribute is a pointer to a recource that contains filenames of patches. The format of this recource is one filename per line optionally followed by a semi-colon (;) and switches for the patch program.
The patch-resource can also be specified in four (4) ways.

new() crates the object. Valid types are single and multi. Valid keys for %args:
* ddir: the build directory
* fdir: the intermediate forest dir (preferred)
* pfile: path to either the patch (single) or a textfile (multi)
* popts: options to pass to 'patch' (-p1)
* patchbin: full path to the patch binary (patch)
* v: verbosity 0..2
config() is an interface to the package lexical %CONFIG, which holds all the default values for the new() arguments.
With the special key all_defaults this returns a reference to a hash holding all the default values.
patch() is a simple dispatcher.
Try to run regen_headers.pl if the flag is set.
patch_single() checks if the pfile attribute is a plain scalar or a ref to a scalar, array, glob. In the first case this is taken to be a filename. A GLOB-ref is a filehandle, the other two are taken to be literal content.
patch_multi() checks the pfile attribute is a plain scalar or a ref to a scalar, array, glob. In the first case this is taken to be a filename. A GLOB-ref is a filehandle, the other two are taken to be literal content.
_make_opts() just creates a string of options to pass to the patch program. Some implementations of patch do not grog '-u', so be careful!
call_patch() opens a pipe to the patch program and prints $$ref_to_content to it. It will Carp::croak() on any error!
