contains a, (not so efficient,) way of checking PROCMAIL.LOG files for
script errors encountered by the procmail(1) program, (the egrep(1)
arguments were taken from the print statements in the error file
distributed in the procmail sources.)

Best strategy is to let procmail run, logging to PROCMAIL.LOG, on a
live system, and watch the size of the PROCMAIL.LOG file, (it can grow
quite rapidly on a busy system,) truncating the file, (rm
PROCMAIL.LOG,) periodically after running procmail.lint.

Procmail.lint only checks for syntactical issues in procmail scripts,
(and not logical errors.)
