Summary description: Draw existential graph invented by Charles S. Peirce
Announcement text: ----------------------------------------------------------------------
`egpeirce` is meant for drawing existential graphs (α, β, and γ systems accounted for) that were invented and developed by the philosopher and polymath Charles S. Peirce (1839--1914). The package also contains novel and unique symbols for multiple types of linear logical operators Peirce invented and used in his larger logical system.
The package enables your document to contain graphs without having to resort to external image files. It also automates many of the more tedious aspects of vectorizing existential graphs by hand. However, it does not check or ensure that proper syntactic rules are obeyed. The graphs are described in relatively simple and straightforward code and when you compile your document, LaTeX (or PostScript through the PsTricks LaTeX package) does the drawing for you.
