+# This script is used to generate the list of fixed bugs that
+# appears in the release notes files, with HTML formatting.
+#
+# Note: This script could take a while until all details have
+#       been fetched from bugzilla.
+#
+# Usage examples:
+#
+# $ bin/bugzilla_mesa.sh mesa-9.0.2..mesa-9.0.3
+# $ bin/bugzilla_mesa.sh mesa-9.0.2..mesa-9.0.3 > bugfixes
+# $ bin/bugzilla_mesa.sh mesa-9.0.2..mesa-9.0.3 | tee bugfixes
+# $ DRYRUN=yes bin/bugzilla_mesa.sh mesa-9.0.2..mesa-9.0.3
+# $ DRYRUN=yes bin/bugzilla_mesa.sh mesa-9.0.2..mesa-9.0.3 | wc -l
+

+trim_after='s/\(show_bug.cgi?id=[0-9]*\).*/\1/'

+
+# extract fdo urls from commit log
