3 # This script compares object files in two directories. Comparisons is done bytewise ignoring
4 # the first 8 bytes of the file ( COFF magic number and time stamp).
5 #
6 # The directories must be specified in a configuration file read by the script. The filename is
7 # passed as the one and only command line parameter.
8 #
9 # The script expects the utility cmp to be in the path.
10 #
11 # The syntax of each line in the configuration file is the following (comments start with #)
12 # <left_directory> <right_directory> <excluded_files> <explicit_files>
13 # <excluded_files> = [-<filename_without_path>]*
14 # <explicit_files> = [+<filename_without_path>]*
15 #
16 # default behaviour (no excluded or explicit files) is to compare all similar named files
17 # inthe two directories
18 # if <excluded_files> are specified these files are excluded from the comparison
19 # if <explicit_files> are specified ONY THESE FILES are included in the comparison
20 #
21 # Attention: file and directory names MUST NOT contain spaces or other white space
