New for V1.1 (5.10.97):
 ReadArgs() interface added, NOIDENT option added, Copyright notice changed.


CompareDirs allows you to compare the directory stucture of two
directories and it compares all files, that can be found in both
directories and all subdirectories, byte by byte.

This is very useful for checking a backup of your harddisk on
CD-recordable or another mass storage medium. Since it really
compares all files, that will be output as identical, byte by byte
you can be sure that no error occured during backing up.

It is also practical to check for differences since the last backup.

And if you have got a new archive of a program you already have,
CompareDirs allows you to check it out for different files.


The calling syntax is:

    CompareDirs <dir1> <dir2> [<resultfile>] [NOIDENT}

or as a argument template: DIR1/A,DIR2/A,RESULTFILE,NOIDENT/S

where dir1 and dir2 are the two directories to be compared and
resultfile is an optional argument that specifies where output
should be written to. By default all output goes to stdout, that
means you will see it in the console window. The NOIDENT switch
allows surpressing output of identical files.


The output looks like:
