# Blueprint to build net-tools-1.60. 
#
# net-tools contains the 'ifconfig' and 'route' utilities that are
# needed to configure network interfaces.  There other useful utilities
# as well.

# the default /usr/src and set SRC_DIR to /root/foo/$PKG_NAME instead.

# This is not one of the packages that can be configured and built
# completely outside of the source tree.  So in order to leave the
# original source untouched, the contents of $SRC_DIR are first copied
# to $BUILD_DIR.  The copy in $BUILD_DIR is then modified to suit the
# configuration.

#
# The configure script for this package does not take any command-line
# options.  Instead, it interactively creates a config.h file that
# contains the configuration options.  Two sed scripts can be used to
# automate the process by deleting all but the relevant lines from
# config.in and putting the results in config.h and then generating
# config.make based on the values in config.h.  This has the effect of
# accepting the default answers to the interactive config questions.
# Additional configuration is done by changing 1 and 0 values for
# certain parameters.
