This directory contains the commutative diagram macros and manual. The macros themselves are in "diagrams.tex". Unlike many other packages there is no "installation procedure" - you just copy this to your TeX macros directory. The manual is provided in several formsts: LaTeX source: diagrams-manual.tex standard DVI: diagrams-manual.dvi 300dpi A4 PostScript: diagrams-manual.ps.Z 300dpi A5 PS booklet: diagrams-booklet.ps.Z The "booklet" form requires a two-sided printer; if you don't have such a thing, don't bother taking the file. "Borceux-to-Taylor.tex" is a *prototype* for emulation of Francis Borceux's macros. The ".Z" suffix means that it's compressed. DVI and compressed files must be transferred in binary mode. If you are fetching this from any site other than theory.doc.ic.ac.uk and have not already done so, please register as a user by sending a message to with the words "commutative diagrams" in the subject line.
