Contrary to (my) assumptions, I actually wrote a program to draw the vowel diagrams like on the IPA chart, instead of the normal “I will! Honest! But later”. Apart from being used to show which symbol means what, the IPA Handbook also uses them to show more accurately what the vowels actually are. This is the intended use of this program, of course, because otherwise you might as well have an image.
For some reason CGI doesn’t work on this server at all. Trying to run things just ends up with the program itself being served, rather than its output. (Yes, I have the executable bit set.) This means that MimeTeX, which is a CGI program written in C, doesn’t work at all.
Of course, this doesn’t really matter since they have a public server, http://www.forkosh.dreamhost.com/mimetex.cgi, which apparently anyone and everyone can use. Of course I feel a little guilty leeching off their site like that even if Adrað’s bandwidth is pretty negligible, so I hacked together a filter for fauxML that uses their server once and saves the result locally. I’ve put the result here so anyone on the other end of a Google search or whatever can save a few minutes’ hassle by copypasting it.
