CLIG(1) Programmer's Manual CLIG(1) 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 in- tent and function. The string one-liner is printed --- besides other sutff --- if the parser encounters an unknown option. Remember to en- close 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.
