+=head1 texloganalyser Documentation
+
+=head2 NAME
+
+texloganalyser -- displays selective infos from TeX log files
+
+=head2 SYNOPSIS
+
+texloganalyser [-efhioprstuvw] tex_log_file
+
+texloganalyser [--version]
+
+texloganalyser [--help]
+
+=head2 DESCRIPTION
+
+Various options may be used to select which information from the TeX log you want to see/analyze (see next section). The default is to display only page numbers (page numbers are B<always> displayed).
+
+=head2 OPTIONS
+
+=over 1
+
+=item B<--version>: displays version information.
+
+=item B<--help>: displays help as a summary of options.
+
+=item B<-e>: displays the end of the log, about the TeX's memory.
+
+=item B<-f>: outputs the LaTeX Font Infos warnings and calculations.
+
+=item B<-h>: outputs only warnings about horizontal boxes.
+
+=item B<-i>: displays 'images' (pdf, [e]ps, png, jpg) used.
+
+=item B<-o>: outputs only warnings about overfull boxes.
+
+=item B<-p>: outputs the LaTeX Packages infos and warnings.
+
+=item B<-r>: displays warnings about references (missing or multiply-defined).
+
+=item B<-s>: displays .sty and .cls files used.
+
+=item B<-t>: displays .tex files used. This option is B<very> useful when you parse logs of master files, to know in which file to look to correct errors/warnings.
+
+=item B<-u>: outputs only warnings about underfull boxes.
+
+=item B<-v>: outputs only warnings about vertical boxes.
+
+=item B<-w>: displays all TeX, LaTeX and font Warnings.
+
+=back
+
+=head2 BUGS
+
+None yet identified. However, the display should be improved...
+
+=head2 HISTORY
+
+This program was first released in 2006. Its purpose was to display selective information of my PhD's TeX log.
+
+=head3 Changelog
+
+=over
+
+=item v0.6: default displays number of warnings (and page numbers).
+
+ added option: references and label warnings
+
+=item v0.5: use of GetOpt::Long and code cleaning
+
+ added options: display of files used
+ improved documentation
+
+=item v0.4: added features and bugs corrections (options h, v, o and u)
+
+=item v0.3: display of Warnings and last lines of the log
+
+=item v0.2: display of "Font Info" and "Packages" added
+
+=item v0.1: first version, displays only warnings about boxes
+
+=back
+
+=head2 AUTHORS
+
+I<texloganalyser> is a program by Thomas van Oudenhove (L<vanouden@enstimac.fr>). Feel free to contact him for features requests or bugs.
