# Script wrmdep
#
# Usage
#     wrmdep [-a | -all | all] [file1 [..fileN]]
#     wrmdep [-o | -old] [[dir1 [..dirN]]
#     wrmdep -update
#
# Description
#     This is a catch-all script for pruning .dep files, depending on the
#     provided arguments.
#
#     [-a | -all | all] [file1 [.. fileN]]:
#     Remove all .dep files from the object directory tree corresponding to the
#     current source directory or remove only the .dep files referring to the
#     optionally specified file(s).  With the -a/-all/all option the .dep files
#     are removed for all platforms rather than just the current platform.
#
#     [-o | -old] [dir1 [.. dirN]]:
#     Remove *.dep files that are without a corresponding .C or .L source file.
#     This occurs when a directory has been moved.
#         - prints the questionable directory and *.dep file
#
#     -update:
#     Search all the "src" and "application" directories of the project for
#     broken symbolic links for source code files and then remove all .dep
#     files that relate to files that no longer exist.
#     Must be executed in the project top-level directory:
#         $WM_PROJECT_DIR.

Usage:

$Script [-a | -all | all] [file1 [..fileN]]

    Remove all .dep files or remove .dep files referring to <file>
    With the -a/-all/all option the .dep files are removed for all
    platforms rather than just the current platform ($WM_OPTIONS).

$Script [-o | -old] [dir1 [..dirN]]

    Remove *.dep files that are without a corresponding .C or .L file.
    This occurs when a directory has been moved.
      - prints the questionable directory and *.dep file

    Note: to remove empty directories, run: wclean empty

$Script -update

    Search all the "src" and "application" directories of the project for
    broken symbolic links for source code files and then remove all .dep
    files that relate to files that no longer exist.
    Must be executed in the project top-level directory:
        $WM_PROJECT_DIR
