# Usage:
# ./otp-get-patches.sh /path/to/otp OTP_R14B01 fedora-R14B01
#
-# Note:
-# We do NOT update erlang.spec or the git index at all.
-# For now, take a look at the patch-list-*.txt files
-# generated in the tmpdir manually copy and adapt them
-# to erlang.spec. Then handle the otp-*.patch files:
+# otp-get-patches.sh - update erlang.spec and otp-00*.patch files
#
-# git rm -f otp-00*.patch
-# mv tmp.foobar/otp-00*.patch .
-# git add otp-00*.patch
+# otp-get-patches.sh updates the erlang.spec and otp-00*.patch
+# files in the git index. After an otp-get-patches.sh run, you
+# will need to review the stage git changes, possibly adapt the
+# Release: and %changelog parts of erlang spec, and can then
+# "git commit" everything.
#
-# We could only automate this if we added the required patch
-# specific spec file conditionals to the commit message somehow,
-# and then had this script transfer the conditionals into erlang.spec.
+# Caution: Leave the four special comment lines untouched in the
+# spec file, as otp-get-patches.sh requires them and will only
+# touch erlang.spec between the respective start/end pair:
+#
+# # start of autogenerated patch tag list
+# # end of autogenerated patch tag list
+# # start of autogenerated prep patch list
+# # end of autogenerated prep patch list
+#
+# The following special comment lines in the git commit messages
+# will be interpreted:
+#
+# Fedora-Spec-Comment: This patch only applies to EL6 builds
+# Fedora-Spec-Before: %if 0%?el6}
+# Fedora-Spec-After: %endif
+#
+# If there is no "Fedora-Spec-Comment:" line, we will use
+# "Fedora specific patch".
