NAME

checkeq − check files that use eqn(1) or neqn(1)

USAGE

checkeq [ files ]

DESCRIPTION

Eqn is a troff(1) preprocessor for typesetting mathematical text on a phototypesetter.  Neqn is used for the same purpose with nroff(1) on typewriter-like terminals.  A line beginning with .EQ marks the start of an equation; a line beginning with .EN marks the end of an equation.  Neither of these lines is altered, so they may be defined in macro packages to get centering, numbering, etc.  It is also possible to designate two characters as delimiters.  Subsequent text between delimiters is then treated as eqn input.  The left and right delimiters may be the same character; the dollar sign is often used as such a delimiter.  Delimiters are turned off by "delim off".  All text that is not between delimiters or between .EQ and .EN passes through untouched. 

Checkeq reports missing or unbalanced delimiters and .EQ/.EN pairs.
