| SHEF2CSV by Will Pearson | |
| A simple C program for converting tab separated UoS module timetable data to Google | |
| .csv format. | |
| Usage: redirect stdin/stdout, e.g. | |
| $ ./shef2csv < input.txt > output.csv | |
| Notes: | |
| - issue with week number ranges. Duplicate lines to remove ranges before running. | |
| - no special handling of empty cells | |
| To Do: | |
| - convert "lastname,firstname" to "firstname lastname" | |
