describe -- Display a description of the named task(s) or package(s).
The describe task is a shortcut for viewing only the DESCRIPTION section of a help file for any STSDAS task or package. It produces the same output as you would get by typing "help task section=description", but offers a more intuitive way of getting the information.
For example, you could type "describe fits.st*" and descriptions would be displayed for both the strfits and the stwfits tasks in the fitsio package since both these tasks match the specified template. In practice, you may not wish to specify more than one task at a time because the descriptions will be concatenated rather than being separated.
If no package name is specified (with the "."), the task assumes you are looking for a task in the current package. The standard pattern matching metacharacters, i.e., "*?", are permitted in patterns. Simple patterns are assumed to be abbreviations.
1. Describe the grpcopy task in the tools package:
cl> describe tools.grpcopy or cl> describe grpcopy or cl> describe grpc
2. Describe the dqfpar and noisepar tasks in the wfpc package. Send the output to your default printer.
cl> describe wfpc.*par | lpr
On some systems, typing the next command keystroke before the end-of-page prompt is printed may result in the character being echoed (messing up the output) and then ignored when raw mode is enabled for the prompt.
