Name of contribution: subdepth Author's name: Will Robertson Location on CTAN: /macros/latex/contrib/subdepth/ Summary description: Unify math subscript height License type: lppl
Announcement text: ---------------------------------------------------------------------- This package is based on code posted to c.t.t. by Donald Arseneau long ago to equalise the height of subscripts in maths. The default behaviour is to place subscripts slightly lower when there is a superscript as well, but this can look odd in some situations. ----------------------------------------------------------------------
