# "make extensions" from the top-level directory.

|

# To add a new extension object, simply copy your module's .c file
|
|
# to this directory, and it will be built automatically using
|
|
# the "standard" compile line. If that compile line does not
|
|
# suffice, create a .mk file with the same prefix as the .c file,
|
|
# and that makefile will be invoked.
