# (such as CLEANFILES or CLEANDIRFILES), or possibly a list of

# variable names. ${.ALLSRC:@v@${${v}}@} will be the list of
|
|
# files to delete. (We pass the variable name, e.g. CLEANFILES,
|
|
# instead of the file names, e.g. ${CLEANFILES}, because we don't
|
|
# want make to replace any of the file names with the result of
|
|
# searching .PATH.)

# If the list of file names is non-empty then use "rm -f" to
|
|
# delete the files, and "ls -d" to check that the deletion was
|
|
# successful. If the list of files is empty, then the commands
|
|
# reduce to "true", with an "@" prefix to prevent echoing.

# both .OBJDIR and .SRCDIR.
