<p><tt>This is a python interface to Adobe Font Metrics Files. Although a<br>
number of other python implementations exist (and may be more complete<br>
than mine) I decided not to go with them because either they were<br>
either<br>
<br>
1) copyighted or used a non-BSD compatible license<br>
<br>
2) had too many dependencies and I wanted a free standing lib<br>
<br>
3) Did more than I needed and it was easier to write my own than<br>
figure out how to just get what I needed from theirs<br>
<br>
It is pretty easy to use, and requires only built-in python libs<br>
