# NOTE 1:
#	At this moment i will only use the nrpe daemon
# NOTE 2:
#	The nagios plugins will follow. First get this working

# to change the commands here.  Patches to the source code are also
# applied in this target as required.
#
# This target also configures the build within the build directory.
# Flags such as LDFLAGS and CPPFLAGS should be passed into configure
# and NOT $(MAKE) below.  Passing it to configure causes configure to
# correctly BUILD the Makefile with the right paths, where passing it
# to Make causes it to override the default search paths of the compiler.
#
# If the compilation of the package requires other packages to be staged
# first, then do that first (e.g. "$(MAKE) <bar>-stage <baz>-stage").
#
# If the package uses  GNU libtool, you should invoke $(PATCH_LIBTOOL) as
# shown below to make various patches to it.
