	Message written at 18 May 1999 11:57:04 +0100 is all ready to go, except I have one problem -- which is the one Anders alluded to, how to locate the string database. My current code looks in the current directory, which is hardly satisfactory. It woudl be possible to look in /usr/local/lib on unix, or use an environment variable, or use then SADIR/SSDIR/... stuff. I would rather not link into the binary, as I was people to have the ability to change language with ease. Oh well..... Version 3.54 is now on the Bath server for PC (3 versions) and Irix4. Sources in both zip and compressed tar are there also. Irix5 and Solaris will follow soon, and Mac68K in a day or so.

	I think the latest PMac version is V3.51.

If so, then any speed differences would have to be do the sound card driver, I would think, no? I don't see how there could be this much of a difference, if the SCHED_RT is working. Ah, I see that the program below doesn't take SCHED_RT priority - that is probably why it is so slow.
