* TEST PROGRAM
*
* testtcp test termcap functions
*
* KEY WORDS
*
* test routines
* termcap test
*
* SYNOPSIS
*
* testtcp [-efns] terminal [capability [capability ...]]
*
* -e => expand string capability given by -s
* -f => determine boolean capabilities for terminal
* -n => determine numeric capabilities for terminal
* -s => determine string capabilities for terminal
*
* terminal => terminal name as given in termcap file
* capability => a boolean, numeric, or string capability
*
* NOTE: All capabilities must be of same type, as
* given by [-fns].
*
* If terminal is only argument then entire entry is
* printed.
*
* DESCRIPTION
*
* Provides way to test termcap functions. Can find
* and print an entire termcap terminal entry, or various
* capabilities from the entry.
