Summary description: Substitution notation with a switchable convention
Announcement text: ------------------------------------------------------------------------
substnote is a new package for the notation of substitution. Textbooks write “the result of substituting t for x in phi” in half a dozen ways, and the two slash conventions are mirror images of one another. The package provides one command and lets the convention be chosen once in the preamble, so that a manuscript can be retargeted without editing the formulas.
------------------------------------------------------------------------
The package’s Catalogue entry can be viewed at https://ctan.org/pkg/substnote
The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/latex/contrib/substnote/
