   8# To run the entire git test suite using fsmonitor:
   9#
  10# copy t/t7519/fsmonitor-all to a location in your path and then set
  11# GIT_FSMONITOR_TEST=fsmonitor-all and run your tests.
  12#
  13
  14# Note, after "git reset --hard HEAD" no extensions exist other than 'TREE'
  15# "git update-index --fsmonitor" can be used to get the extension written
  16# before testing the results.
