Ok, here's a little hack: An AWP file reader in C. It's just something I
whipped up in a few hours, so don't expect a filecard interface. Feel free
to add/subtract/multiply features yourself. Don`t forget to FTP your AWP files
in binary mode.
Also, it seems that I'm going to be the new archivist for apple2.archive, so
let me know if you have any suggestions.
Features:
- prints all OA-O options as '--Printer Option' (almost like AppleWorks)
- prints all char control codes as '^' (just like AppleWorks)
- prints all tab rulers as text (i.e. ===>===) (sort-of like AW)
- does not interpret tab rulers, margins, etc.. (nothing like AW)
- minimal error checking (like AW, NOT!)
- should work will all versions
- only reads stdin (i.e. 'a.out < FILE.AWP')
- written in just a few hours
- throughly tested on 2 AWP files
- but hey, what do you want for free?
