~/idl/vlib/--+-- color/     Create, Load, Manipulate, Save color tables.
             |			(some are extensons of IDL standard library)
             |
             |-- deconv/    Deconv_Tool is main routine which applies methods
             |			of image restoration (deconvolution with
             |			max_likelihood, max_entropy, sigma-clean,
             |			max_residual_likelihood, ...)
             |
             |-- graphics/  Rubber-box graphics, marks of various shapes, 
             |			hardcopy, color scale with cursor interaction...
             |
             |-- image/     Image array storage, manipulation, and processing.
             |			(storage of images in pooled array, statistics,
             |		         cross-correlation, profiles, patching,...)
             |
             |-- io/        Locating files, some input/output of files.
             |			(these are independent of operating system)
             |
             |-- math/      optimization, integration, interpolation, 
             |			approximation, vectorized math, etc....
             |			(minf_conj_grad and related routines for
             |			 finding minimum of N-dimensional function,
             |			 Trp3d is 3D array transpose,...)
             |
             |-- misc/      for strings, conversion, sorting, queries...
             |			(get_words is quite general)
             |
             |-- models/    astrophysical models: IR spectrum of dust emission,
             |			simple radiative transfer, escape probability...
             |
             |-- struct/    for structures: copying, comparing, checking...
             |			(with many recursive options)
             |
             +-- widgets/   Compound draw-widget, misc widget utilities,...
             |
             +-- window/    Create/Manipulate/Zoom/Print/Delete windows...
             |
             +-- xdoc/      doc = Widget for browsing thru all routines in path,
             |			code obtained from Dominic Zarro, Solar physics.
             |
             +-- 386i/	Code for Sun386i only, frozen at idl version 2.0.4
