Various Ant tasks used during the NetBeans build process.

Of especial interest to module developers are:

`<makenbm>`
`<genlist>`
  Create NBM files for Auto Update, and create update tracking files to list the files contained in an NBM.
`<jhindexer>`
`<checklinks>`
`<checkhelpsets>`
  Create search databases for JavaHelp help sets. Check those help sets, or any other sets of HTML files, for broken links.
`<arch>`
  Create a high-level architectural summary of your module and how it interacts with the complete application, based on a premade XML-based questionnaire.

Of especial interest to those creating a complete NetBeans distribution:

`<createmodulexml>`
  Pregenerate the files `system/Modules/*.xml` in a NetBeans distribution, so that they are not created in the user directory when NetBeans is first started.
`<makeupdatedesc>`
  Create an XML file which can be put on a webserver that Auto Update can connect to in order to get a list of NBMs that it can install - create your own update center.
