overview

This is the documentation for the `IDLdoc project <http://idldoc.idldev.com>` 
source code. The source code can be accessed via Subversion with the command::
  
   svn co http://svn.idldev.com/idldoc/trunk idldoc

An IDLdoc run passes through three stages:

  1. parsing: uses the appropriate classes in the `parser` directory to parse 
     source files and the comments contained in them to create a tree of 
     objects, found in the `tree` directory, representing IDL constructs
  
  2. processing: analyze the tree created in step 1 to create connections 
     between objects, the index, etc.
  
  3. generating output: the templating mechanism found in the `templating`
     directory uses the appropriate templates in the `templates` directory to 
     produce the output
     
IDLdoc uses a "system" object that contains all the top-level information 
about a run. The `IDLDOC` routine itself is only a thin wrapper around the 
creation of the system object. The system object has methods corresponding to 
the three stages of the run: `parseTree`, `process`, and `generateOutput`.

Profiler statistics for the run that produced these API docs can be found
`here <profiler.html>`.

:Dirs:
   ./ 
      main-level programs such as IDLdoc itself, the system object, and the 
      version function
  
   analysis
      routines used to calculate proper scaling for the visualization of data 
      in a `.sav` file (external)
      
   cmdline_tools
      used to produce color text output, if available and desired (external)
      
   collection 
      collection classes (external): `MGcoArrayList` and `MGcoHashTable` are
      used extensively
      
   dist_tools 
      routines for handling distributing applications like `MG_SRC_ROOT` and
      `MG_CMP_VERSION` (external)
      
   dist_tools/collection
      not needed since `collection` is already a direct external for IDLdoc

   dist_tools/objects
      not needed since `objects` is already a direct external for IDLdoc
         
   introspection 
      routines for providing information about an IDL variable (external)
   
   objects
      routines and classes required for handling collection classes in IDL 
      8.0 (external)
      
   parser 
      parser classes for parsing `.pro`, `.dlm`, `.sav`, `.idldoc` files, and
      the comments contained in them into a tree of IDL constructs using the
      classes in the `tree` directory 
      
   templating 
      template class and its helpers (external); this is the library which is
      able to fill in the blanks in the templates in the `templates` directory
      when IDLdoc is in the generating output stage
      
      The `tree` classes are passed directly to the templating engine when 
      IDLdoc is producing output. They are queried by the templating engine
      via their `getVariable` method.
      
   textmarkup
      classes to convert a markup tree to a particular markup language 
      (external)
      
   tree
      classes representing IDL constructs such as directories, files,
      routines, etc.; the goal of the parsing stage of an IDLdoc run is to 
      create the tree of IDL constructs
      
      Each class in the `tree` directory has `fillLinks` and `lookupName`
      methods used during the processing stage of an IDLdoc run. Each class
      also has a `getVariable` method so that it can be queried for
      information by the templating engine.
      
   util 
      utility routines/classes (formatting integers, etc)
