- Make patches against the latest version of the manual page.
Use git(1) for getting the latest version.
+ Prepare the patches for email submission
+ We recommend using git-format-patch(1) to prepare the patches.
+ Please use --range-diff to document the differences between
+ revisions of the patch set, even in the first revision.
+
+ To prepare a branch to be sent as a patch set (v1):
+
+ $ git format-patch -o ./patches master..HEAD \
+ --range-diff=master -v1 --cover-letter;
+
+ The range diff will be included in the cover letter (or in a
+ single patch, if there is only one):
+
+ $ tail -n7 ./patches/v1-0000-cover-letter.patch;
+ Range-diff against v0:
+ -: --------- > 1: 7ec952012 foo.3: tfix
+ -: --------- > 2: d80376b08 bar.3: ffix
+ -: --------- > 3: 892a12470 foo.3: wfix
+ --
+ 2.43.0
+
+ To send a v2 after some feedback:
+
+ $ git format-patch -o ./patches master..HEAD \
+ --range-diff=old_master..old_HEAD -v2 --cover-letter;
+
+ The values for 'old_master' and 'old_HEAD' can be consulted in
+ the previous cover letter. In this example, it would be
+ '--range-diff=7ec952012^..892a12470'.
