| 7 # This script is used to compare vpx_config.h and vpx_config.asm to |
| 8 # verify the two files match. |
| 9 # |
| 10 # Arguments: |
| 11 # |
| 12 # -h - C Header file. |
| 13 # -a - ASM file. |
| 14 # -p - Print the options if correct. |
| 15 # -o - Output file. |
| 16 # |
| 17 # Usage: |
| 18 # |
| 19 # # Compare the two configuration files and output the final results. |
| 20 # ./lint_config.sh -h vpx_config.h -a vpx_config.asm -o libvpx.config -p |
