Appy contains several utility programs, most of them lying in appy/bin. This section describes some of these programs. When Appy is installed, executable appy (currently not available under Windows) is added to the path (as already stated here): every utility program described in the following sub-sections is available as a appy sub-command. 
If you type appy in a shell, you'll get something like this: 
  
if you want to launch program appy/bin/ogrep.py, you must simply type: 
appy ogrep 
Every such program has option -h, allowing to output its documentation. 
appy ogrep -h 
As noted in the screenshot, an alternate, equivalent syntax is: 
appy help ogrep  |
