# flag_parse implements a robust flag parser.
#
# For a full fledge example see ../examples/date.sh
#
# It differs from getopts(1) in that long form options are supported. Currently the only
# deficiency is that short combined options are not supported like -xyzq. That would be
# interpreted as a single -xyzq flag. The other deficiency is lack of support for short
# flag syntax like -carg where the arg is not separated from the flag. This one is
# unfixable I believe unfortunately but for combined short flags I have opened
# https://github.com/terrastruct/ci/issues/6
#
# flag_parse stores state in $FLAG, $FLAGRAW, $FLAGARG and $FLAGSHIFT.
# FLAG contains the name of the flag without hyphens.
# FLAGRAW contains the name of the flag as passed in with hyphens.
# FLAGARG contains the argument for the flag if there was any.
#   If there was none, it will not be set.
# FLAGSHIFT contains the number by which the arguments should be shifted to
#   start at the next flag/argument
#
# After each call check $FLAG for the name of the parsed flag.
# If empty, then no more flags are left.
# Still, call shift "$FLAGSHIFT" in case there was a --
#
# If the argument for the flag is optional, then use ${FLAGARG-} to access
# the argument if one was passed. Use ${FLAGARG+x} = x to check if it was set.
# You only need to explicitly check if the flag was set if you care whether the user
# explicitly passed the empty string as the argument.
#
# Otherwise, call one of the flag_*arg functions:
#
# If a flag requires an argument, call flag_reqarg
#   - $FLAGARG is guaranteed to be set after.
# If a flag requires a non empty argument, call flag_nonemptyarg
#   - $FLAGARG is guaranteed to be set to a non empty string after.
# If a flag should not be passed an argument, call flag_noarg
#   - $FLAGARG is guaranteed to be unset after.
#
# And then shift "$FLAGSHIFT"
