A HelpStudio project contains all the information necessary to build a Help System. Every HelpStudio project contains:
Conceptual Topics, including Topic content, links and index keywords;
A Glossary containing Glossary terms and related definitions;
A Table of Contents;
One or more Build Profiles that each define a particular output you want to produce from the project;
Zero or more Build Flags that can be used in Build Profile Rules to conditionally include items and content in a Build Profile;
Images, Stylesheets and Other Files;
Each project can optionally contain additional locales. Additional locales allow you to author content for multiple languages within a single project.
A HelpStudio project exists in a project directory that contains the main project file (with a .hsp extension), together with any project specific Image or other external files.
