# Start script for Hattrick Organizer v0.31
# Originally created by patta, RAGtime and others
# Last Change (2005-08-07) by Lars Engels (lars@bsd-geek.de)
#
# List of changes:
#
# 0.32 - optional separate configuration file
# 0.31 - configurable java memory (-m or $MAX_MEMORY)
# 0.3 - Introduce the bourne shell as standard shell
# - Make HO! multi-user capable
# - Several layout changes to the script
# - check database before doing backup
# - quit if java version is not returned (NO Sun java?)
#
# changed for Mandriva packages:
# using jpackage features for java
########################################################################
# #
# User editable settings #
# #
# To use HO! with multiple users on one system: #
# - create a new directory, e.g. /usr/local/share/hattrickorganizer #
# or /opt/ho and unpack the HO archive there! #
# #
# - copy HO.sh to a directory in users $PATH, e.g. #
# cp HO.sh /usr/local/bin/ho #
# #
# - optionally you may create a HO.config file there and edit #
# this instead of HO.sh #
# #
# - edit the HODIR variable to this new directory (without the ``) #
# and HOHOME to any user writable directory! #
# #
# - start HO! out of a terminal via e.g. 'ho' #
# #
# - manage your team :) #
# #
# #
# Alternatively, as single user just start HO! from the HO directory #
# via ./HO.sh without editing something! #
# #

# of the following variables later if it exists in HO.sh-directory.

#
# Enter HO!'s directory. Default is the current directory.
# In multi user mode this can be any directory (full path!).
#
#HODIR=`pwd`

# Next comes HO!'s directory to store its user data.
# This directory must be writable by the user,
# default is install directory (single user mode).
#
# SINGLE USER:
#
#HOHOME=$HODIR
#
# MULTI USER:
#
HOHOME=~/.hattrick-organizer
# Where can I find java?
# Default is just looking at $PATH
# (remember option -j)

# Default is 5
#
#MAX_BACKUPS=5

# Enter the maximum amount of memory available to the java VM.
# Default is 256 MegaBytes!
#
#MAX_MEMORY=256m

# Read additional user configuration variables from config file and
# overwrite the defaults above if it is found in HO.sh-directory !!!
