If this switch is enabled, hdbexamine will print a detailed description
of the help database listing the modules in each package, the date the entry
for the package was last modified, and other information. A more concise
summary listing only the packages and the number of help modules in each
package is printed by default.
The hdbexamine task is used to examine the contents of a help database. By default the standard IRAF help database is examined. Examining the help database with hdbexamine verifies that it can be read by help, and may be useful as a diagnostic in the event that an invalid help directory file (".hd") somewhere in the help directory tree, causes the database to be compiled incorrectly.
1. Print a concise summary of the contents and structure of the standard help database.
