version 0.4

This script was made for web directory listing.
Install it by copying this file into /perl/lib or some other directory
in @INC. You have to set your webserver to use also default.plx
(or some other name of a perl script).

Make a file default.plx in all directories you want to show.
The file will contain only some options and
  require 'weblist.pl';

Options :

$heading = The <TITLE> of the page, default is "Index of <path>"
$message = the HTML code to include on top of the page.
$footer = the HTML code to include on bottom of the page.

$showicons = 0/1, whether to show the icons
$showdate = 0/1, whether to show the last modification date
$showsize = 0/1, whether to show the file size
$showdescription = 0/1, whether to show the description
$showname = 0/1, whether to show the icons
 all these options default to 1

$noupdir = 0/1, should we show '..'? Default is 1.

$style = 'SIMPLE'/'EXTENDED', the SIMPLE style doesn't show the form with options and
         file masks.

$head_name = the heading for file name column
$head_date = the heading for date column
$head_size = the heading for file size column
 all these options defalut to English.

$q{dir} = the default for the select list on the page
  0 - Directories shown with files
  1 - Directories shown before files
 -1 - Directories shown after files
  2 - Only files
  3 - Only directories

$q{file} = the default filename mask, eg. "*.ppd"

$q{grep} = the default perl regexp, eg. "\.ppd$"


A description for a $file is to be written into file "$file.dsc".

Example:
 Authent-0.2.1.tar.gz
 Authent-0.2.1.tar.gz.dsc

 where Authent-0.2.1.tar.gz.dsc contains
    Request HTTP authentification if a condition fails
