Installing the guestbook-script is quite simple:

1. Copy the script to the directory dedicated for your server's cgi-scripts.
2. Create a file to store the guest-book entries in somewhere on your server.
   If cgi-bins are executed with UID and GID nobody, this file should have 
   permisions 0666. If cgi-bins are executed with a specific UID and/or GID,
   let this user/group own the file and give it the permissions 0664 or 0644.
3. Decide, if you want the form, the user has to fill out to submit a new
   guest-book entry, in the guest-book file or in a separate file. If you
   want it in a separate file, create this file now. See below to learn,
   what parameters the cgi-bin understands. An example is provided with
   addguest.html
4. Create an html-file for the guest-book. Somewhere in this file, you should
   include the guest-book entry file, you have created, using server side
   includes (SSI). guestbook.shtml is provided as an example.
5. Create another plain html-file, which is displayed, when an error
   occured, while executing the cgi-bin. Currently the only case, this may
   happen, is when the user didn't fill out the comment field. Normally,
   you will give the use another chance to submit an entry by supplying the
   submit-form again. This file is often quite similar to the file created
   in 3 (if you decide to have a separate file). In this case you don't have
   to create a separate file here.
6. Open the cgi-bin with your favourite text-editor. Adjust the path to your
   perl interpreter at the top of the file. Also adjust the variables,
   defined below the header (see the script-file for more information).

The cgi-bin understands the following arguments:

name    - the name of the signer
email   - his/her e-mail address
url     - his/her homepage, if only "http://" is supplied, this is ignored
city    - the city the signer lives in
country - the country the signer lives in
comment - the comment

At least the comment has to be supplied. See addguest.html for an example.
