The JavaHelp libraries and tools are located in the javahelp folder 
  of the release. All classes work with the Java 2 Platform, Standard Edition 
  (J2SE) and use Swing 1.2 or later (included in the J2SE). 
 The JavaHelp classes are distributed in the following four JAR files located 
  in the javahelp\lib folder:
| jh.jar | The standard library, which includes everything needed to use the standard navigator types (TOC, index, full-text search). | 
| jhbasic.jar | A subset of jh.jarthat does not include support for the 
      full-text search engine. This subset might be useful for very simple help 
      systems that do not require a full-text search database or for help systems 
      in which size is critical. | 
| jhall.jar | Contains all the JavaHelp system classes, including the tools required to create a search database. | 
| jsearch.jar | Contains the default full-text search engine used in the JavaHelp system. | 
 The JavaHelp tools are used to view helpsets and to build and query the full-text 
  search database. These tools are located in the javahelp\bin folder. 
| jhindexer | Command-line program that creates the full-text search database used by the JavaHelp system full-text search navigator to locate matches. | 
| jhsearch | Command-line program that queries the JavaHelp system full-text search 
      database that is created with the jhindexercommand. You can 
      usejhsearchto test a search database without invoking the 
      help viewer. |
