clig_Usage

NAME

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.
