# Commentary:
# ===========
#
# set cal-tex-diary to true so that diary entries show up in the calendar 
#
# Usage:
# ======
#
# run this makefile with 
#
#  make -f org2hpda
#
# The makfile will take the entries from your diary file and generate
# two PDFs containing nicely printed weekly and monthly calendars. One
# is done in the style of a pocketMod (http://www.pocketmod.com/) and
# the other is done in the style of the Hipster PDA
# (http://en.wikipedia.org/wiki/Hipster_PDA). 
#
# Requirements:
# =============
#
# the pdf* commands are part of the pdfjam package which can be found
# at http://www.warwick.ac.uk/go/pdfjam

# Number of weeks to be printed. Should be a multiple of 4, because 4
# of them are merged on one page. Can be set when invoking the script
# as follows: make NUMBER_OF_WEEKS=8 -f org2hpda
NUMBER_OF_WEEKS = 4
