pick any ast command that uses optget() or script that uses getopts
and this will give the usage string
ast-command --usage
if you have the ast fmt(1) command (from the ast-open package)
then use the -o option to format the usage
fmt --usage 2>&1 | fmt -o
the ast ls(1) command exercises most of the optget/getopts features
ls --usage 2>&1 | fmt -o
you can stuff this into a ksh script for testing with getopts
astcmd=ls
{
print -r $'USAGE=$\''
$astcmd '--??usage' 2>&1 | fmt -o
print $'\n\'\ngetopts -a '$astcmd$' "$USAGE" OPT'
} > test-$astcmd
chmod +x test-$astcmd
test-$astcmd --man
