About the CMS Muon Trigger slides

Introduction

Transparencies presented at various meetings are the primary communication medium in CMS. Almost every information appears first just in this form. Therefore it is extremally important to provide a quick and easy access to this information for all interested people. The WWW offers very convenient way of getting it. However providing the information i.e. writing html is painful and time consuming process. Even more difficult is maintenance of a big and complicated structure which is in fact a kind of data base.

Facing all this problems I have made an attempt to facilitate these tasks and build a tool for semiautomatic maintenance of a transparencies archive. The purpose of this work was just to make my life easier rather then create a general and powerful system. Therefore the structure is rather stiff and all the scripts are full of explicite names. The style is rather "amateur" than professional. However knowing that many other people have similar problems I decided to publish my work even if it cannot be very useful in its present form. My hope is that somebody will take the ideas and create a nice utility in more professional way.

Description of the system

Assumed structure (created "by hand")

Transparencies are primarily stored as single page Post Script files.
They are arranged in a three level structure of UNIX directories.
Each level 1 and 2 directory contains a file called .dirtitles of the following format:
```
 
    dirname1   title1
    dirname2   title2
    ...
 
```
The title can consist of a few words separated by spaces.
Each level 2 and 3 directory contains a file called .filetitles of the following format:
```
 
    filename1   title1
    filename2   title2
    ...
 
```
The filename is the name of a Post Script without .ps.

Features of the system

The system performs the following tasks:

converts Post Script to GIF,
creates a html page for every transparency,
creates a html page for every directory,
packs all the files into a tar archive to be moved to a WWW server.

These tasks are done by a set of UNIX scripts:

Do_titles and Do_titles23 - facilitates preparing .dirtitles and .filetitles files
Do_cutlink - removes standard SGI link prefix link_to_
ps_gif - converts Post Sript to GIF using the ImageMagick system by John Cristy (cristy@dupont.com) available by anonymous FTP from ftp.x.org as contrib/applications/ImageMagick/ImageMagick-3.1.tar.gz.
Do_checkgif - checks whether there is a corresponding GIF and mini-GIF for every Post Sript file
Do_html creates a html page for every transparency
Do_www creates a html page for every directory
Do_find loops over all Post Sript files calling above scripts

All the scripts are appended here.
