# The purpose of this script is to record the configuration of
# the currently installed opera.  Ideally, you can just re-run this
# script to re-install Opera.

# The script tries to get opera installed into the correct locations,
# and patch the install so that plugins (java) work.

# Please update this variable, if opera updates.
# It should match the substring embedded in the directory name, 
# e.g.: opera-9.10-20061214.1-static-qt.i386-en-521
opera_version=9.10-20061214.1
