# Introduction

This document describes how to use the HTMLDOC software, version 1.8.16. HTMLDOC converts Hyper-Text Markup Language ("HTML") input files into indexed HTML, Adobe® PostScript®, or Adobe Portable Document Format ("PDF") files.

HTMLDOC supports most HTML 3.2 elements, some HTML 4.0 elements, and can generate title and table of contents pages. It does not currently support stylesheets.

HTMLDOC can be used as a standalone application, in a batch document processing environment, or as a web-based report generation application.

No restrictions are placed upon the output produced by HTMLDOC.

## History

Like many programs HTMLDOC was developed in response to a need our company had for generating high-quality documentation in printed and electronic forms. For a while we used FrameMaker® and a package from `sgi` that generated "compiled" Standard Generalized Markup Language ("SGML") files that could be used by the Electronic Book Technologies ("EBT") documentation products (EBT is now owned by INSO.) When `sgi` stopped supporting these tools we turned to INSO, but the cost of their tools is prohibitive to small businesses.

In the end we decided to write our own program to generate our documentation. HTML seemed to be the source format of choice since WYSIWYG HTML editors are widely (and freely) available and at worst you can use a plain text editor. We needed HTML output for documentation on our web server, PDF for customers to read and/or print from their computers, and PostScript for our own printing needs.

The result of our efforts is the HTMLDOC software which is available for UNIX® and Microsoft® Windows®. Among other things, this software users manual is produced using HTMLDOC.
