All it needs to do is read from a specified file, find the From lines, and 
generate appropriate output.  Sounds like 20 or 30 lines of code.  Could 
use lexer_fgets() which accepts NUL characters.  Being dumb, it could 
assume "^", i.e. only match lines if the search string is at the beginning 
of the line.
