## @fn build-guacamole.sh
##
## Builds Guacamole, saving "guacamole.war" and all applicable extension .jars
## using the incubator-guacamole-client source contained within the given
## directory. Extension files will be grouped by their associated type, with
## all MySQL files being placed within the "mysql/" subdirectory of the
## destination, all PostgreSQL files being placed within the "postgresql/"
## subdirectory of the destination, etc.
##
## @param BUILD_DIR
##     The directory which currently contains the guacamole-client source and
##     in which the build should be performed.
##
## @param DESTINATION
##     The directory to save guacamole.war within, along with all extension
##     .jars.  Note that this script will create extension-specific
##     subdirectories within this directory, and files will thus be grouped by
##     extension type.
