# TODO wish-list:
# - Generic function for evaluating version numbers
# - Generic function(s) to extract stuff from our own meta-data
# - Logging function which automatically adds resource identifier etc

# TODO: Move more common functionality for OCF RAs here.

# Portability comments:
# o The following rely on Bourne "sh" pattern-matching, which is usually
# that for filename generation (note: not regexp).
# o The "*) true ;;" clause is probably unnecessary, but is included
# here for completeness.
# o The negation in the pattern uses "!". This seems to be common
# across many OSes (whereas the alternative "^" fails on some).
# o If an OS is encountered where this negation fails, then a possible
# alternative would be to replace the function contents by (e.g.):
# [ -z "`echo $1 | tr -d '[0-9]'`" ]
