             Tar/Gzip archive : ewla.tar.gz (0 Ko)
             DOS Zip format   : ewla.zip (0 Ko)

    What this archive contains ?

            This archive comes with different files:
                - COPYING:       Copyright informations (GPL).
                - README:        This file.
                - LISEZMOI:      French doc...
                - ewla.pl:       Perl Launcher.
                - ewla_logan.pl: Log Analyzer program.
                - ewla_graph.pl: Report Generator.
                - ewla.cfg:      Config File (default).
                - ewla_fr.cfg:   Config File translated to french.
                - ewla.lg:       English language support file (default).
                - ewla_fr.lg:    French  language support file.
                - ewla_mk_help.pl : Program used to make help cards.
                - ewla_cal.cgi:  CGI calendar
                - present/html   Images and statics pages directory.
                - present/templates    Templates pages directory.

    How does it works:

            Do nothing, it just launch 'ewla_logan.pl' and 'ewla_graph.pl'.

            1) Parse web log file for each new days and store result into
        resume directory (actually 1 file by day).
            2) Read days data files and calculate sum for each month beginning.
            3) Read months data files and calculate sum for each year beginning.

            Read each news or modified resumes data files and create report for
        this news days.

    If you want to use it for daily report day by day, It should be
        recommended to it with 'ewla_cal.cgi' module. This module make automatically
        links for calendar without recalculate all report. To use copy index_cgi.html
        into index.html and edit 'ewla_cal.cgi' file for configure it (Same info that
        'ewla.cfg' file)

    Installation and Configuration:

        It's a Perl script, so installation is pretty easy. You don't need to
    compile anything.

    Edit config file (ewla.cfg) :
            read comment and change defaults values if needed...

    Copy statics pages and images :
            copy 'present/html/*' into your report result directory

    Launch 'ewla_mk_help.pl' to create helps card.

    Optional : change default reports presents. See section 7.

    How to run it ?

        ewla.pl [Options]
        Options :
            -c file,    --conf-file file      config file name (default ewla.cfg).
            -l file,    --log-file file       log file name.
            -rd dir,    --res-dir dir         name resume dir.
            -od dir,    --out-dir dir         name output dir.
            -v,         --version             output version information and exit.
            -h,         --help                display help and exit.

    How to change look ?
