Program

This package can be used to manage the execution of external programs from PHP.

It can build a command line string to execute an external program synchronously or in background, pass switches to define program options, and define the program input or output files.

It also supports using driver classes that can build complex command line switches to simplify the definition of program options in a simplified way.

include_once 'Program.php';
