|

#
|

# The following environmental variables are set by this utility:
|
||||
#
|
||||
# RD_SOURCE - The path to the top of the Rivendell source tree.
|
||||
# RD_LANGUAGES - The path to the top of the languages tree.
|
||||
# This a working folder for your translation files.
|
||||
# RD_SHAREDDIR - The path to Rivendell's shared data directory
|
||||
# /usr/local/share/rivendell by default
|
||||
# /usr/share/rivendell on Ubuntu
|
||||
#
|
||||
## IMPORTANT NOTE: This script must be run in a special way. The best
|
||||
## is if you run it from the /helpers folder with the following command:
|
||||
## . ./setenvvar.sh
|
||||
## If the first .(period) and space are omitted the script will run but
|
||||
## environmental variables will not be set.
