remctl 2.7

Finally got this out. It was like pulling teeth in part because I decided to finally write some test cases for the ACL and config file parsing, which I'd been putting off. I'd been putting it off because it's an annoying bit of code. But I finally pushed through.

This version also cleans up the select loop around commands and decides the command is finished when it exits rather than waiting for standard output and standard error to be closed. This should help considerably when using remctl to start or restart long-running daemons. There are various other minor bug fixes included as well.

You can get the latest version from the remctl distribution page.
