Required external libraries
|
||||
---------------------------
|
||||
|
||||
The viztool code requires the following external Java libraries (JAR
|
||||
files) to be placed here in the lib/ directory or in the shared library
|
||||
directory specified in the build.xml file (${java.libraries}).
|
||||
|
||||
* samskivert library:
|
||||
http://www.samskivert.com/code/samskivert/
|
||||
|
||||
Once the jar files are in place (regardless of what they are named), the
|
||||
build system will automatically include them in the compile-time
|
||||
classpath.
