Commutative diagrams[edit]

For those who are interested in how I make the commutative diagrams that I have uploaded here: I use Paul Taylor's diagrams package for TeX along with John Walker's textogif Perl script for converting the TeX to PNG's. I believe the script makes use of the Netpbm library for doing the graphics conversions. (I do all of this on Windows with cygwin and MiKTeX; of course, it should all work fine under Linux).
