Jens Grivolla commented on UIMA-2121:
-------------------------------------

The thing is that jOpt quite easily gives functionality like the following:

$ java -jar PearInstallCLI.jar -?

Option                                  Description                            
------                                  -----------                            
-?, -h                                  show help                              
-c, --check, --verify                   do verification                        
-d, --dir <File: directory (default:    installation directory                 
  use PEAR name)>                                                              
-f, --file <File: filename>             PEAR file                              
-v, --verbose                           be more verbose

Reproducing all this manually would probably make the program several times 
bigger.  While I agree that having an external dependency only to parse three 
command line arguments (-v isn't actually used currently, and -h doesn't count) 
is overkill, I probably won't have time in the next few weeks to rewrite it.

> There should be a way to install PEARs without having to use the GUI 
> PearInstaller.  This is especially important when installing all needed PEARs 
> for a project, or doing a clean reinstall.
