+1  LaCheck
+
+A consistency checker for LaTeX documents.
+
+	LaCheck filename[.tex]
+
+2 DESCRIPTION
+
+LaCheck is a general purpose consistency checker for LaTeX documents.
+It reads a LaTeX document and displays warning messages, if it finds
+bad sequences. It should be noted, that the badness is  very
+subjective.  LaCheck is designed to help find common mistakes in LaTeX
+documents, especially those made by beginners.
+
+The things checked are: Mismatched groups (braces), environments and
+math mode delimiters.  When a mismatch is found, line numbers for
+"both"  start and end of the mismatch is given. The error messages
+comes in pairs, one for the end match and one for the beginning,
+marked with `<-' and `->' respectively.
+
+Bad spacing including missing a `\' after an abbreviation, missing an
+`\@' before a punctuation mark in a paragraph that is ended by an
+capital letter, double spaces like ` ~', bad usage of ellipsis (like
+using ... instead of \ldots, or using \ldots where \cdots should be
+used), missing \~ before a \cite or \ref commands, space before
+footnotes, italic corrections before comma, point, or italic text,
+italic correction after normal text, missing italic correction when
+switching from italic to normal text, and double italic correction.
+
+Badly placed punctuation marks around end of math mode delimiters.
+This is, pucktuation placed right after display math end or
+punctuation placed right before text math end.  Sequences of
+whitespace followed by punctuation marks are also caught. Bad use of
+quotation characters, i.e. constructs like "\'word" or "word\`" are
+warned about, tabs in verbatim environments are caught, certain TeX
+primitives are frowned upon, attempts to give font specifiers
+arguments such as \em{text} are noted, and use of @ in LaTeX macros
+are reported.
+
+LaCheck will read files that are input using \input or \include. Files
+with suffix `.sty' are omitted, as they probably will cause LaCheck to
+crash.
+
+2 USAGE
+
+	LaCheck filename[.tex]
+
+LaCheck may be invoked from within Emacs using compile:
+
+To run:  
+"M-x compile RET lacheck RET"
+, and then 
+"C-x `"
+to parse the messages
+
+2 OUTPUT 
+
+The output is UNIX-error like, and may be parsed using Emacs compile
+mode. Here is a sample:
+
+0
+lacheck compiler
+
+"/usr/mef/compiler.tex", line 34: missing `\' after "etc."
+
+"/usr/mef/compiler.tex", line 179: double space at " ~"
+
+"/usr/mef/compiler.tex", line 186: <- unmatched "}"
+
+"/usr/mef/compiler.tex", line 181: -> unmatched "$$"
+1
+
+A control space `\\ ' should be inserted at line 34, to prevent an
+end-of-sentence space. 
+Also, at line 179, the first space of the sequence " ~" should
+probably be deleted.
+The last two lines is an example, where the user mistyped, and
+probably inserted an extra "}" somewhere.
+
+2 DIAGNOSTICS 
+
+Some special cases should be explained. In cases where a sentence ends
+with something that LaCheck thinks is an abbreviation an missing `\\'
+error may also occur, if the following sentence begins with a
+lowercase letter.
+
+A mismatch error may cause more to follow, due to the chosen
+algorithm. In such cases just correct the "first" error and run
+LaCheck again
+
+Braces, environments and math mode must be balanced within a file.
+
+LaCheck may be confused by unmatched stuff placed inside verbatim-like
+environments called something else than exactly `verbatim'.

+
+2 BUGS
+
+LaCheck gets confused by advanced macros, is fooled by simple macros,
+can't figure out if you use a non-standard way to switch italic on or
+off, does not like TeX at all, does not provide any options to turn
+off specific warnings, and is at best a crude approximation.
+
+Ideas for improvements and bug reports are very welcome.  Such should
+be directed to the maintainers, their email address is
