Starting +in Version 2.1, some extensions have been added. Also, the User's Manual +has been \TeXified (diagmac2.tex) and expanded, including several +examples. The test file (diagmactest.tex) is as originally released by +Reynolds (but modified to load diagmac2.sty). + +At Reynolds's ftp site, there is the following disclaimer: + + These macros are in the public domain, and have not changed in many + years. Acknowledgement of their usage is not necessary. However, + neither I nor CMU accept any responsibility for the consequences of + errors in these macros or their documentation. This is more than the + usual disclaimer; TeX is a beastly language for programming anything + complex, and I am not an expert in its use, so that there are probably + errors lurking in the macros. + +In fact, after more than 20 years of intensive use by dozens of +enthusiastic users, it seems that not a single error has been +discovered. + +The licence for diagmac2.sty and diagmac2.tex is LPPL. + +Bob Tennent +School of Computing +Queen's University +Kingston, Canada K7L 3N6 +rdt@cs.queensu.ca |
