`users' and `submission' are bound as in `check:', but there is
nothing else special about these. See the description of the
`pre-checker' and `post-checker' values for what can be done with
these, and note that the check for valid users is always first.
> submission-eval
A parameter that holds an evaluation procedure for evaluating code
in the submission context.
> (user-data user)
Returns a user information given a username. The returned
information is a list of strings that corresponds to the configured
`extra-fields' (see above).
> (user-substs user str)
Given a username, this procedure will lookup the user's extra-fields
information (see above) and then substitute field names in {braces}
by the corresponding value. An error will be signaled if a field
name is missing. Also, "{username}" will always be replaced by the
username.
This is used to process the `:student-line' value in the checker,
but it is provided for additional uses. For example, the following
is an example of a post-checker that will send a submission receipt
email with CC to the TA (assuming a single TA), and pop-up a message
telling the student about it:

for `post:' for using this procedure.

This procedure is intended for use as the :users entry in a checker.
It will do nothing if there are two users, and throw an error if
