# This Makefile summarizes .tab data files to .day, .mon, .html

# WARNING: this file contains a .tab dependency on .bin files.  If you
# have files generated by a wx200d version less than 0.7, then many of
# your .tab files may get regenerated!  TO PREVENT THIS, run fixtime
# from the wx200d source distribution before using this Makefile!

# Some of this, especially the functions, is probably GNU make
# specific.  With VPATH set to the data directory, the html can be
# placed in a separate directory by linking this Makefile to there.
# Then an example cron job might look like:

#  5 0 * * * cd ${prefix}/share/wx200d && make > /dev/null
# 25 0 * * * cd ${prefix}/share/wx200d/html && make html > /dev/null

prefix		= /usr/local

# path to the .bin, .tab, .day, .mon data logs:
VPATH := ${prefix}/share/wx200d

# path to the perl scripts that do the conversions:
wxsum	= ${exec_prefix}/sbin/wxsum
wxhtml	= ${exec_prefix}/sbin/wxplot2html
