## @fn 020-download-drivers.sh
##
## Downloads all JDBC drivers required by the various supported databases. Each
## downloaded driver is stored beneath /opt/guacamole/drivers, with symbolic
## links added to the mappings beneath /opt/guacamole/environment to ensure any
## required drivers are added to GUACAMOLE_HOME if necessary to support a
## requested database.
##
##
## Downloads the JDBC driver at the given URL, storing the driver's .jar file
## under the given name and environment variable prefix. The downloaded .jar
## file is stored such that it is pulled into GUACAMOLE_HOME automatically if
## environment variables with that prefix are used.
##
## If the URL is for a .tar.gz file and not a .jar file, the .jar will be
## automatically extracted from the .tar.gz as it is downloaded.
##
## @param VAR_PREFIX
## The environment variable prefix used by the extension that requires the
## driver.
##
## @param URL
## The URL that the driver should be downloaded from.
##
## @param DEST_JAR
## The filename to assign to the downloaded .jar file. This is mainly
## needed to ensure that the drivers bundled with the image have names that
## are predictable and reliable enough that they can be consumed by
## third-party use of this image.
