31 Export a range of applied patches to a given directory (defaults to
32 'patches-<branch>') in a standard unified GNU diff format. A template
33 file (defaulting to '.git/patchexport.tmpl' or
34 '~/.stgit/templates/patchexport.tmpl' or
35 '/usr/share/stgit/templates/patchexport.tmpl') can be used for the
36 patch format. The following variables are supported in the template
39 %(description)s - patch description
40 %(shortdescr)s - the first line of the patch description
41 %(longdescr)s - the rest of the patch description, after the first line
42 %(diffstat)s - the diff statistics
