Simple alternative to IPC::Open3
IPCOpen3Simple aims at making it very easy to start a shell command, eventually feed its stdin with some data, then retrieve its stdout and stderr separately.
When you want to run a shell command and parse its stdout/stderr or feed its stdin, you often end up using IPCRun, IPCCmd or IPCOpen3 with your own parsing code, and end up writing more code than you intended. IPCOpen3Simple is about removing this overhead and making IPCOpen3 easier to use.
IPCOpen3Simple calls IPCOpen3 and redirects stdin, stdout and stderr to some function references passed in argument to the constructor. It does a select on the input/output filehandles returned by IPCOpen3 and dispatches their content to and from those functions.
