NAME
System::Explain - run a system command and explain the result
SYNOPSIS
use System::Explain "command, verbose, errors";
sys qw(ls -al);
The sys function runs a system command, checks the result, and comments on
it to STDOUT.
DESCRIPTION
System::Explain is a standalone release of System, part of Gedcom v1.20 and earlier.
FUNCTIONS
import
Say use System::Explain "list, of, options" to use this module.
The options are: command (to print the command before running it),
error (to report on the exit status), and verbose (to do both of those).
sys
sys(@command); runs @command (by passing @command to system()) and
optionally prints human-readable information about the result (specifically,
about the return value of system()).
Returns the return value of the system() call.
