# CLEANFILES Additional files to remove for the clean and cleandir targets.

# MAKEOBJDIRPREFIX Specify somewhere other than /usr/obj to root the object
|
|
# tree. Note: MAKEOBJDIRPREFIX is an *enviroment* variable
|
|
# and does work proper only if set as enviroment variable,
|
|
# not as global or command line variable! [obj]
|
|
#
|
|
# E.g. use `env MAKEOBJDIRPREFIX=/somewhere/obj make'
|
|

# NOOBJ Do not create build directory in object tree.

# OBJLINK Create a symbolic link from ${CANONICALOBJDIR} to ${.CURDIR}/obj
|

# Note: This BREAKS the read-only src tree rule!
