# Groc (Googley runner of commands) is a microlanguage that provides an
# alternative to traditional cron syntax/semantics for specifying
# recurrent events.  Syntactically, it is designed to be more readable
# (more easily 'grokked') than crontab language.  Groc forfeits certain
# semantics found in crontab, in favor of readability; however,
# certain timespecs which are awkward in crontab are much easier
# to express in Groc (for example, the 3rd tuesday of the month).
# It is these constructs to which Groc is best suited.
#
# Examples of valid Groc include:
# '1st,3rd monday of month 15:30'
# 'every wed,fri of jan,jun 13:15'
# 'first sunday of quarter 00:00'
# 'every 2 hours'
#
# FEATURES NOT YET IMPLEMENTED (in approx. order of priority):
# - some way to specify multiple values for minutes/hours (definitely)
# - 'am/pm' (probably)
# - other range/interval functionality (maybe)
