I wound up using some of the APS macros, and a number of things I wrote.
For me, the cool part of this is that my thesis was built using a multi-pass makefile. I ran it on all of my machines (SGI Indy, OS2 laptop) at the time.
Since then I've written documentation for 2 projects in LaTeX. It worked quite well, but then I was forced into using the dark side's tools (Word) as none of my colleagues were versed in the finer side of (La)TeX.
I'm sure LaTeX has a lot of super tricky stuff that does really good stuff and was too much work for me to implement, but with LaTeX if something went wrong then I'd be stuck-o since I would not be able to debug LaTeX.
So, TeX it is. If there are bugs in my macros, then I fix the bugs.
Yes, I got around to TeX in about 1998 on OS/2. Now on Windows, It's my standard for all more serious word whacking, of course, especially for anything mathematical.
My TeX setup has a converter from TeX's DVI file type to PDF, and my Adobe Acrobat reader can print to FAX, and my computer has a FAX modem card I run my land line phone through. So, net, I can send letters from TeX to Congress!
I prefer TeX! And I've published applied math with just TeX, sent to Information Sciences, an Elsevier journal, and they handled the TeX source easily!
I prefer TeX because Knuth's book is shorter and easier to read than the books on LaTeX.
Yes, for TeX I wrote about 100 macros for table of contents, cross references, help with bibliographies, ordered, unordered, and simple lists, boxes around text, etc.
So, it's not all just LaTeX guys -- TeX is still darned nice!
Nothing comes between me and my TeX!
Give up TeX? It will have to be pried out of my cold, dead fingers!
