All of the above, taken together.

One starts with parsing key-value arguments in TeX macros, then further features are required, and you start adding features to the LaTeX macros for list processing and the like, and before you know it something has arise that is too complicated for TeX macros.

CVS, as I recall, started as shell scripts to support concurrent use of RCS.  But after a while, shell scripts are no longer suitable.

Hope this helps.
