This lets you set environment variables in a test case. Usage is setenv "FOO" "bar" which will set FOO=bar if FOO does not already exist. There is also an optional '-force' argument, which will overwrite the current variable if already set: setenv -force "FOO" "baz" The force argument corresponds to passing a non-zero third argument to setenv(3).
