Examples

  <patch patchfile="module.1.0-1.1.patch"/>

applies the diff included in module.1.0-1.1.patch to the files in base directory guessing the filename(s) from the diff output.

  <patch patchfile="module.1.0-1.1.patch" strip="1"/>

like above but one leading directory part will be removed. i.e. if the diff output looked like

--- a/mod1.0/A	Mon Jun  5 17:28:41 2000
+++ a/mod1.1/A	Mon Jun  5 17:28:49 2000

the leading a/ will be stripped.
