Helper script to build source from scratch

[Tim Funk]

For anyone still getting up to speed using svn and making a new build -  here 
 is script which works for me via cygwin. It should work fine in any unix 
environment too.

Steps
- Place the script in an empty directory.
- Make sure ANT_HOME and JAVA_HOME are set
- Make sure svn is in your path
- Run the script and the svn checkout  as well as the download and full build 
will be done.

Since there is a /current/ alias - is the 'ant update' task needed anymore?

# This is a quickie helper script to  easily build tomcat 5 from source.
# This will create a subdirectory called tc5build and build
# tomcat 5 into it.
#
# Here are the requirements to get this to run
# 1) Set JAVA_HOME to a 1.4 compliant JDK
#     ex: /opt/java1.4
# 2) Set ANT_HOME to your ant installation (You need ant 1.6 or better)
#     ex: /opt/jakarta/jakarta-ant-1.6
# 3) Make sure svn is in your path
# 4) Make sure NetComponents.jar is installed in $ANT_HOME/lib
#    which can be found at http://www.savarese.org/oro/index.html
#    [Not sure if this step is still required for Ant to download things.]
