# This script is used to help test konsolekalendar.
#
# Modify $konkal, $cal, and $TCM as necessary for your needs.
#
# Requirements:
# lynx
# konsolekalendar (from KDE).
# Date-Calc perl module (from CPAN).
#
# Options: -d, delete entries from KDE calendar file
# -c, change entries in KDE calendar by re-writing movie titles in all caps.
# -m <month>, where month is an integer 1 thru 12
# default is current month
# -y <year>, where year is an integer YYYY
# default is current year
# -f <file>, where file is location of output KDE calendar
# default is $HOME/.kde/share/apps/korganizer/tcm.ics
# -w <konsolekalendar> where konsolekalendar is located
