cvs commit: jakarta-tomcat/src/share/org/apache/tomcat/startup Jspc.java

  Added:       src/share/org/apache/tomcat/startup Jspc.java
  Log:
  A new startup class, wrapping JspC. It'll set the classpath and all that's needed
  to run it. This simplifies the shell scripts ( and it'll also work for platforms
  where .sh or .bat are not present ).
  
  Jspc was broken in 3.3b1 ( at least on unix ). I didn't tested it too much, but
  it starts and seems to be fine.
