Developers need to learn parsing tools anyway, but that's not much of
an argument since the only parsing tools you need for handling simple
config files are fgets(3), strchr(3), and strtok_r(3). In languages
like Perl and Python it's even easier.
If the syntax (as opposed to the semantic content) of your config file
requires more than a couple paragraphs in its man page to describe,
you're probably doing something wrong.
