# Script
#     wmake/scripts/wcleanObjects
#     Backend for "wclean -build", "wclean -platform"
#
# Usage
#     wclean-build <option | platform> [.. <option | platform>]
#
# Description
#     Deletes the specified 'build/' object files directories from the
#     project top-level 'build/' directory $WM_PROJECT_DIR.
#
#     special platforms
#     - 'all' removes all platforms.
#     - 'compiler' corresponds to $WM_ARCH$WM_COMPILER.
#     - 'current' corresponds to $WM_OPTIONS.
#
#     You must be in the project or the third-party top-level directory
#     to run this script.
#
#     When called as wcleanPlatform, the target directory changes to
#     'platforms/ and the 'all' target also cleans up lnInclude dirs and
#     tutorials
#
#------------------------------------------------------------------------------

Usage: ${0##*/} <option | platform> [.. <option | platform>]

options:
  -a | -all             Same as 'all'

Deletes specified $targetDir object file directories from project top-level:
Project:   $WM_PROJECT_DIR
Directory: $targetDir/

special platforms:
  all           Remove all platforms$extraText
  compiler      $WM_ARCH$WM_COMPILER  (ie, \$WM_ARCH\$WM_COMPILER)
