<note from moderator: Thanks to Hans for mentioning xypic. The tar files for it are now located in the [anonymous.categories.macro] directory at macc2.mta.ca. So are the TeX source files and documentation for Mike Barr's, Francis Borceux' and Paul Taylor's diagram macros. A pointer to David Jones TeX macro index is included in the ftp site list. Bob> Dear Bob, In your latest note on posting in categories@mta.ca you mentioned [.macro]. For diagrams in TeX I'm using XY-pic which is probably the most extensive diagram package available, and quite "user-friendly", too. Moreover, the author is supporting the package. It is listed in DM Jones' "styles-and-macros.Index" as: Name: xypic.tex Description: Macros for typesetting diagrams. Keywords: plain TeX, AMS-TeX, LaTeX, XY-pic, diagrams, graphics, commutative diagrams. Author: Kristoffer H. Rose <kris@diku.dk> Supported: yes Latest Version: v2.6, 24 Jun 1992 Note: Comes with extensive documentation (xypicman.doc) which requires AMS-TeX, xppt.tex, xfixed.tex and xrcs.tex to format. (The manual is also distributed preformatted.) XY-pic also requires several special fonts (xyatip10.mf, xybtip10.mf, xyline10.mf and xymisc10.mf) which are distributed with the package. Numerous other files are also included. Archives: aston, stuttgart, utrecht, shsu, ftp.diku.dk* [/pub/TeX/misc/xypic*] and is probably best available via ftp to diku.dk in TeX/misc/xypic. It has previously been announced on the news net. By the way, you might also consider including the "styles-and-macros.Index". I append the distribution message in the end of this mail. yours, Hans ------------------------------------------------------------------------------
