usage: crc_galore.py [-h] [-p] [-l | -c CODE | -f FILE]

Calculates the CRC Sums for a given file. Useful to find the algorithm used
for a given file and checksum without reverse engineering.

optional arguments:
  -h, --help            show this help message and exit
  -p, --permutate       Permutate to create non-standard configuration
  -l, --list            List available CRC Algorithms
  -c CODE, --code CODE  Output C-Code for given CRC Algorithm
  -f FILE, --file FILE  Calculate CRCs for given file
