4.4 Checking for problems
=========================
Running TeX or LaTeX will only find regular errors in the document, not
examples of bad style. Furthermore, description of the errors may often
be confusing. The utilities 'lacheck' and 'chktex' can be used to find
style errors, such as forgetting to escape the space after an
abbreviation or using '...' instead of '\ldots' and other similar
problems. You start 'lacheck' with 'C-c C-c Check <RET>' and 'chktex'
with 'C-c C-c ChkTeX <RET>'. The result will be a list of errors in the
'*compilation*' buffer. You can go through the errors with 'C-x `'
('next-error', 
(emacs)Compilation), which will move point to the
location of the next error.
Each of the two utilities will find some errors the other doesn't,
but 'chktex' is more configurable, allowing you to create your own
errors. You may need to install the programs before using them. You
can get 'lacheck' from
'<URL:ftp://ftp.ctan.org/tex-archive/support/lacheck/>' and 'chktex'
from '<URL:ftp://ftp.ctan.org/tex-archive/support/chktex/>'.
