# This is a hack to maintain some semblance of backward compatibility with
# the old, Perl-based glib-mkenums. The old tool had an implicit ordering
# on the arguments and templates; each argument was parsed in order, and
# all the strings appended. This allowed developers to write:
#
#   glib-mkenums \
#     --fhead ... \
#     --template a-template-file.c.in \
#     --ftail ...
#
# And have the fhead be prepended to the file-head stanza in the template,
# as well as the ftail be appended to the file-tail stanza in the template.
# Short of throwing away ArgumentParser and going over sys.argv[] element
# by element, we can simulate that behaviour by ensuring some ordering in
# how we build the template strings:
#
#   - the head stanzas are always prepended to the template
#   - the prod stanzas are always appended to the template
#   - the tail stanzas are always appended to the template
#
# Within each instance of the command line argument, we append each value
# to the array in the order in which it appears on the command line.
