# This is a small install script to install
# leo on GNU/Linux. 
# Leo is Open Software and is distributed under the terms 
# of the Python License.  Please see:
# docs/LICENSE.TXT for details.
#
# This install script created by Frank Merenda 
# (fmerenda@yahoo.com)
#
# verison 1.0 - 06/30/2003
# - initial creation 
#
# 
# - minor changes to try and use a "prefix" directory
# - step 5 copies the src and config directories as 
# directories rather that file (this seems to prevent
# the need to remove ".." from the python scripts on RH9
# anyway.)
# - IMPORTANT NOTE: I did not understand step 6 so its
# commented out. Someone who knows leo better than I do
# should look at this.
# - Note: I'm a leo newbie so I don't know if this fixes plugin
# problems since I don't think I use them.
