The main point of this is to provide documentation
when you get the following error in the cron logs
after trying to run a gulp task:

/usr/bin/env: node: No such file or directory

Resolves #2033.

Typically, within a cron job, you want to run any binary using absolute paths,
so an initial approach to running `gulp build` every minute might look like:

* * * * * cd /your/dir/to/run/in && /usr/local/bin/gulp build

Oh that is a cron thing. Before the actual command you want to run, you have to specify the schedule for the command. That is, how often a command should run:

# ┌───────────── minute (0 - 59)
# │ ┌───────────── hour (0 - 23)
# │ │ ┌───────────── day of month (1 - 31)
# │ │ │ ┌───────────── month (1 - 12)
# │ │ │ │ ┌───────────── day of week (0 - 6) (Sunday to Saturday;
# │ │ │ │ │                                       7 is also Sunday on some systems)
# │ │ │ │ │
# │ │ │ │ │
# * * * * *  command to execute

Per What does * * * * * (five asterisks) in a cron file mean?,

Every minute of every day of every week of every month, that command runs.

I figured I would use that rather some some arbitrary "run once a day at midnight" or something.
