Yodl

Syntax seems pretty basic. If a word is ended by parenthesis then that is an argument. Multiple arguments involve multiple parenthesis in sequence. Putting a backslash at the end of a line marks that line for continuation.

Conversion process seems to be intertwined with the output format. Became less interested when I found the postprocessor is somewhat language specific rather than being a generic two-pass system.

No real sensible scapes. If you want a character Yodl claimed for itself--too bad. You have to use char(..) with a numeric code to get it.

Going to pass on this. Texinfo's @magic{} and Booklit's \magic{} is good enough.
