# Usage: <file>
# <left file> <right file>
# Either normalizes a file or compares two of them in a side-by-side
# diff.
#
# Checks environment variables:
#
# CLIENT_TEST_SERVER=funambol|scheduleworld|egroupware|synthesis
# Enables code which simplifies the text files just like
# certain well-known servers do. This is useful for testing
# to ignore the data loss introduced by these servers or (for
# users) to simulate the effect of these servers on their data.
#
# CLIENT_TEST_CLIENT=evolution|addressbook (Mac OS X/iPhone)
# Same as for servers this replicates the effect of storing
# data in the clients.
#
# CLIENT_TEST_LEFT_NAME="before sync"
# CLIENT_TEST_RIGHT_NAME="after sync"
# CLIENT_TEST_REMOVED="removed during sync"
# CLIENT_TEST_ADDED="added during sync"
# Setting these variables changes the default legend
# print above the left and right file during a
# comparison.
#
# CLIENT_TEST_COMPARISON_FAILED=1
# Overrides the default error code when changes are found.
