NAME

       whiff - like which, but finds the first of all the given alternatives

USAGE

	whiff <command ... >

DESCRIPTION

       which is a useful utility, found on most unix systems.  It gives you the absolute path for the first occurance of a program in your path.
       Unfortunately, it does two stupid things:  first, if it can't find one, it prints an error message to stdout; secondly, if you give it
       multiple arguments, it assumes you want one line per argument, each like calling which individually.

       whiff assumes that all the arguments form a best-first list of alternatives, and only prints the path to the first alternative found in the
       path.  If none is found, it prints an error (to stderr!) and exits with an error code.

NAME

       Package::Reaper - pseudo-garbage-collection for packages

VERSION

       version 0.103

SYNOPSIS

	   use Package::Generator;
	   use Package::Reaper;

	   {
	     my $package = Package::Generator->new_package;
	     my $reaper  = Package::Reaper->new($package);
	     ...
	   }

	   # at this point, $package stash has been deleted

DESCRIPTION

       This module allows you to create simple objects which, when destroyed, delete a given package.  This lets you approximate lexically scoped
       packages.

INTERFACE

   new
	 my $reaper = Package::Reaper->new($package);

       This returns the newly generated package reaper.  When the reaper goes out of scope and is garbage collected, it will delete the symbol
       table entry for the package.

   package
	 my $package = $reaper->package;

       This method returns the package which will be reaped.

   is_armed
	 if ($reaper->is_armed) { ... }

       This method returns true if the reaper is armed and false otherwise.  Reapers always start out armed.  A disarmed reaper will not actually
       reap when destroyed.

   disarm
	 $reaper->disarm;

       This method disarms the reaper, so that it will not reap the package when it is destoryed.

   arm
	 $reaper->arm;

       This method arms the reaper, so that it will reap its package when it is destroyed.  By default, new reapers are armed.
