Not yet :). I noticed using
source (should be .)
== (should be =)
${BASH_SOURCE[0]} (should be $0)
$UID (should be $(id -u)
bash redirection &>> (should be >/dev/null 2>&1)
+= (should be VAR="${VAR}foo")
and bash shebang.

Could you please fix that?

Can we, please, use /bin/sh and not-expect bash?
Portability matters.

Can be just echo. Maybe using cat might be better than many echos:

cat <<EOF
Usage:
\tevmtest runtest <test name> [OPTIONS]
...
EOF


Kind regards,
