CError
Run cerror on a source code file of a compiled language to get the length of the outputted error compared to the filesize. Some people try to get the largest error with the smallest file, this script gives you a score for this.
Use (in general)
#include __FILE__
The sample file is above, this is a small amount of source but produces a large error. This would get a really good score because of that ratio of code to error.
Use (the script)
./cerror -f main.c -c g++
./cerror -f filename
-c compiler name
