LaCheck is a tool for finding potential errors in LaTeX documents.
LaCheck catches many errors LaTeX will ignore, and LaCheck generally
gives better error messages.  Think of it as lint for LaTeX.

LaCheck should work on any Unix system that `flex' has been ported to.
It may also work on other systems, I wouldn't know.  In particular, no
DOS binary of this version is available, but a DOS binary for version
1.8 is available.  LaCheck is available for anonymous ftp from:

host: ftp.iesd.auc.dk
file: /pub/TeX/LaTeX/lacheck.tar.gz	(Unix source for version 1.15)
file: /pub/TeX/LaTeX/lachec18.zip	(DOS binary for version 1.8)

Here is the log of changes since version 1.8:
