# Makefile for efabless project open_pdks
# Tim Edwards, 11/21/2016
# Updated 10/19/2018 for use independently of the
# efabless /ef/ tree filesystem setup.
# Updated 5/5/2020 for use with the 2-stage install
#---------------------------------------------------
#
# Typical usage:
#
# make
# 	generates the tech files from source masters.
#
# make install
#
# 	installs the tech files.  If the configuration
#	script has been given the "--with-<PDK>-dist-path="
#	option, then tech files are installed in the path
#	(such as a git repository) that is used for
#	distribution of software across a system.  Otherwise,
#	files are installed in the local path specified by
#	the configuration option "--with-<PDK>-local-path=".
#
# make clean
#
# 	clean up all files generated by 'make'
# 
# make veryclean
#
# 	clean up all files generated by 'make' and remove
#	all log files.
#
# make uninstall
#
#	remove the installed PDKs.
#
# make reference
#
#	annotate the technology JSON file with the current
#	commit state of all repositories used by the PDK to
#	create a reference set of PDKs.  Can be used with
#	the configure --with-reference option to compile
#	to sources from a specific set of commits.
