667	<patch> element support for download and uncompression	kpfleming@…	kpfleming@…	"<patch> element should be extended to support the following:

<patch>
    <file>path-to-patch-file</file>
    <digest>md5-or-other-sum-of-file</digest>
    <reference>URL-to-get-patch-file</reference>
</patch>

The element will then download the file if necessary, checks its digest, and
issue the patch command as follows:

patch -N -p1 path-to-patch-file

in the current or specified <base>, of course. If the file is compressed, it
will be decompressed as it is passed to the patch command (just as the <unpack>
element does). Should support a <mode> attribute, of ""forward"" (the default) or
""reverse"", and also a <strip> attribute (default of 1). Any other patch options
can be specified by using <param> attributes, which will be appended to the
constructed command line.

Issues:

- should this be syntax version 3.2?

- should this be a new element name, or is changing the existing element acceptable?"	enhancement	closed	lowest		nALFS - Back End (XML Handlers)	SVN	minor	fixed
