# The 'rake/clean' file defines two file lists (CLEAN and CLOBBER) and
|
|
# two rake tasks (:clean and :clobber).
|
|
#
|
|
# [:clean] Clean up the project by deleting scratch files and backup
|
|
# files. Add files to the CLEAN file list to have the :clean
|
|
# target handle them.
|
|
#
|
|
# [:clobber] Clobber all generated and non-source files in a project.
|
|
# The task depends on :clean, so all the clean files will
|
|
# be deleted as well as files in the CLOBBER file list.
|
|
# The intent of this task is to return a project to its
|
|
# pristine, just unpacked state.
