<!--
  A utility ant script get the eclipse builder from Git. 

  Hudson jobs can call this script from ant as one of it first build steps.
  Such as, start with a wget fetch from CGit (where following $dash; is literally a '-',
  it is escaped here just for XML rules against two dashes in a comment);

  curl -o getEBuilder.xml https://download.eclipse.org/eclipse/relengScripts/testScripts/bootstrap/getEBuilder.xml

  Then use ant to invoke the functionality. Example:

  ant -f getEBuilder.xml
