See [`dependency()`](#dependency) for argument format. +The version of the program is determined by running `program_name --version` +command. If stdout is empty it fallbacks to stderr. If the output contains more +text than simply a version number, only the first occurence of numbers separated +by dots is kept. If the output is more complicated than that, the version +checking will have to be done manually using [`run_command()`](#run_command). |
