NAME:  dirdiff

Find the difference between two directories.

SYNOPSIS:

  dirdiff [options] from-dir to-dir

OPTIONS:

  -h, --help  --  Print help text and exit.
  -q          --  Quiet mode, only print which files are different.
  -u          --  Use the -u option on the actual diff command.

DESCRIPTION:

This command can find the difference between two directories.  It
looks at all files in the specified directories (recursively), doing
diff's between those files.  It will list files that are in one
directory but not the other, and will optionally display the
differences between files that are in both directories.

For example, to determine the difference between a local 'd0reco' area
and one in D0 release pxx-xx-xx, you could do

  dirdiff d0reco /d0dist/dist/releases/pxx-xx-xx/d0reco

To get just a list of what files are different, try

  dirdiff -q d0reco /d0dist/dist/releases/pxx-xx-xx/d0reco

The command uses the 'native' diff command when comparing files.  If
you would like to use 'diff -u', then use the -u option:

  dirdiff -u d0reco /d0dist/dist/releases/pxx-xx-xx/d0reco

This command ignores sub-directories named CVS.
