New Revision: 1100553
URL: http://svn.apache.org/viewvc?rev=1100553&view=rev
Log:
Add a simple test shell script that will execute and gauge basic
operations on increasingly large directories in working copies.
It supports ra_local and svn protocols as well as valgrind usage.
Users may need to adapt the paths at the beginning of the script.
