A rust version of cron-wrap
This is mostly the same implementation as cron-wrap, but without the SMTP options. Those may be added later, but for now, this should be fully usable for most cases.
See cwrap --help for all of the various options here.
An important note about CLI parsing: If you have options for your command,
you must terminate the options for cwrap with a --. For example,
if you were going to run grep -R something /path/to/dir/* and you wanted to
set a cwrap option like --num-fails, you would do it like this:
bash
cwrap --num-fails 3 -- grep -R something /path/to/dir
Unfortunately, clap will gobble up anything that looks like an option no matter where it is, unless the options are terminated.
