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.
