This file exists in order to create the "subdir-b" subdirectory.  There is
exists sibling directory "subdir" that is a prefix of this subdirectory.
This file exists for self-testing.

This file exists in order to provide Fossil with a test case of a file
that is deeply nested below many subdirectories.

<h2>Changes For Version 1.30 (as yet unreleased)</h2>
  *  Add setting to control the number of times autosync will be tried before
     returning an error.
  *  Add the "fossil fusefs DIRECTORY" command that mounts a Fuse Filesystem
     at the given DIRECTORY and populates it with read-only copies of all
     historical check-ins. This only works on systems that support FuseFS.

<h2>Changes For Version 1.29 (2014-06-12)</h2>
  *  Add the ability to display content, diffs and annotations for UTF16
