I'd like to put in a plug for having the tz string in the binary file preceded by @(#) so that it appears when the what(1) utility is invoked.
Does anyone still run systems with "what" or sccs on it?
Yes (to the former, not the latter), although that's beyond the point. (It ships under MacOS and I have it on other systems, including Solaris and NetBSD). But the idea is to have the string displayable using a semi-standard tool. That doesn't preclude doing something snazzier. An argument could be made that ident(1) is a better choice, although I don't think it really is, in part since it would require assigning a pseudokeyword like $Tz: ... $.
I stopped using "what" strings many years ago when "what" stopped being available on systems. There does appear to be a package available called cssc which is compatible with sccs.
The BSD version is easily available. --jhawk@mit.edu John Hawkinson
