EQNCHAR(7)

✨ NAME ✨

okay so this is eqnchar(7) from the BSD System Compatibility corner of the manual set, and it is literally the special character definitions for eqn, bestie. eqnchar is the file in question. 🫶

🌸 SYNOPSIS 🌸

Two whole pipelines, pick your fighter:

eqn /usr/share/heirloom-doctools/pub/eqnchar [files] | troff [options]

neqn /usr/share/heirloom-doctools/pub/eqnchar [files] | nroff [options]

💖 DESCRIPTION 💖

eqnchar contains troff and nroff character definitions for constructing characters that are not available on the Graphic Systems typesetter. These definitions are primarily intended for use with eqn and neqn. periodt. 💅
