NAME
::clig::Usage - declare single line usage-string
SYNOPSIS
package require clig
namespace import ::clig::*
setSpec db
Usage one-liner
DESCRIPTION
The Usage command specifies a one line description of the program’s
intent and function. The string one-liner is printed --- besides other
sutff --- if the parser encounters an unknown option. Remember to
enclose one-liner in braces. A (not so) typical example would be
Usage {program to delete your home directory}
In fact, the one-liner can be longer than one line. Best results are
obtained, if one-liner is not put in braces but is surrounded by double
quotes. The quoted string may than contain newlines. Clig automatically
adds backslashes where necessary in the generated C-code so that the C-
compiler does not go wild.
