-## Convert INN configuration files to the current syntax.
-##
-## Intended to be run during a major version upgrade, this script tries to
-## convert existing INN configuration files to the syntax expected by the
-## current version, if that's changed.
-##
-## Note that this script cannot use innshellvars.pl, since loading that file
-## requires innconfval be able to parse inn.conf, and until this script runs,
-## inn.conf may not be valid.
-##
-## Currently handles the following conversions:
-##
-## * Clean up inn.conf for the new parser in INN 2.4.
-## * Add the hismethod parameter to inn.conf if not found.
