CTAN Update: sseq
This is a minor bug fix that corrects displaying errors for curved lines in current versions of pgf/tikz. The deprecated "snake" library is no longer used, in favor of the path decoration library
This package is located at http://mirror.ctan.org/macros/latex/contrib/sseq . More information is at http://www.ctan.org/pkg/sseq (if the package is new it may take a day for that information to appear). We are supported by the TeX Users Group http://www.tug.org . Please join a users group; see http://www.tug.org/usergroups.html .
Thanks for the upload. For the CTAN Team Rainer Schöpf
sseq – Typesetting spectral sequence charts
The package provides commands to draw spectral sequence diagrams, providing facilities for clipping and arranging multiple symbols so that they do not overlap. The package is built using pgf, and shares that systems large demands for TeX system memory. Its geometric commands are based on a turtle graphics model, and control structures such as loops and conditionals are available.
