#!/bin/bash
# Usage:
#    ./otp-get-patches.sh /path/to/otp OTP_R14B02 fedora-R14B02
#
# otp-get-patches.sh - update erlang.spec and otp-00*.patch files
#
# 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 staged git changes, possibly adapt the
# 'Release:' and '%changelog' parts of erlang.spec, and can then
# "git commit" everything.
#
# Caution: Leave the four special comment lines untouched in the
# spec file, as otp-get-patches.sh requires them and will only
# touch the parts of erlang.spec between the respective start/end
# comment 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".
