# Detect is a package is installed or in a database
# Checks for package, if -T returns non-zero output, egrep will return 0
# because it finds it, so we negate the value to say it's not built.
# -Sp works backwards, it will print output only when the package already
# exists
# Example usage: is_built "pcre>=20"
