Added:
proposal/myrmidon/src/java/org/apache/myrmidon/framework/exec/launchers
ScriptCommandLauncher.java PerlCommandLauncher.java
Log:
Converted the old remaining useful script based CommandLaunchers to new
setup. There is no need to extend ProxyCommandLauncher as it did not offer any
benefit (because the 2 arg version of Runtime.exec was always called)
