whereis 3.11.2

I guess I failed to create releases for a while.

3.10.0:  Linux compatibility, Python 2 compatibility, finally implemented
         /b (oops), fixed /c command output to console, fixed /e, /a
         outputs file permissions on Linux
3.10.1:  Cython support
3.10.2:  whereis now catches FileNotFound exceptions when trying to get
         file information on files that are write-locked.
3.10.3:  whereis now catches OSError exceptions, which are thrown when,
         for instance, a file has the name "CON".
3.11.0:  added /y to search for duplicate files and /w to add extra source
         directories to search
3.11.1:  added /?! to display the help file for the /c mini specification
         language, and modified the options to be more consistent
3.11.2:  /?! didn't work.  I also changed it to /!.

whereis 3.9.11 - line truncation is off by default, allow for multiple /i and /x

updated readme

whereis 3.9.10 - calling other programs doesn't block any more

changed from os.system( ) to subprocess.Popen( ) for /c, which doesn't block
