markem.py

markem.py is a driver script for egrade.py. markem.py takes as arguments a list of student directory names to be graded. Typical usage is:

markem.py  *

where * is the Unix file wildcard.

If no arguments are given, a usage message is printed and the script exits.
If any argument is not a directory name in the current working directory, it is skipped.
To determine the files to be graded, the script reads the grading key file key.cfg; if the file does not exist, the script prints an error message and quits.
For each file to be graded category and directory userid, the script executes:
```
egrade.py  category  userid
```
provided a file named category exists in the students directory. For example, my test script generates a file named compile.log containing compiler error messages; the file is deleted by the testing script if it is empty; in this case being missing means that no compile error marks need be applied. Ditto for the late marks.
For a given category the script iterates over all directories before moving on to the next category (file to be graded).
In an attempt to resume grading where one left off, the script skips directories (students) and grade files which have already been graded. The file time stamps are used to determine if the log file is newer than the graded log file.
Currently to force a regrade in a single category for a student, invoke egrade.py directly.
To totally regrade a student, delete all the students *.grd files.
To grade or re-grade a single category:
```
markem.py -c catgeory  *
```
