-=head1 NAME
-
-User::grent - by-name interface to Perl's built-in getgr*() functions
-
-=head1 SYNOPSIS
-
- use User::grent;
- $gr = getgrgid(0) or die "No group zero";
- if ( $gr->name eq 'wheel' && @{$gr->members} > 1 ) {
- print "gid zero name wheel, with other members";
- }
-
- use User::grent qw(:FIELDS;
- getgrgid(0) or die "No group zero";
- if ( $gr_name eq 'wheel' && @gr_members > 1 ) {
- print "gid zero name wheel, with other members";
- }
-
- $gr = getgr($whoever);
-
-=head1 DESCRIPTION
-
-This module's default exports override the core getgrent(), getgruid(),
-and getgrnam() functions, replacing them with versions that return
-"User::grent" objects. This object has methods that return the similarly
-named structure field name from the C's passwd structure from F<grp.h>;
-namely name, passwd, gid, and members (not mem). The first three
-return scalars, the last an array reference.
-
-You may also import all the structure fields directly into your namespace
-as regular variables using the :FIELDS import tag. (Note that this still
-overrides your core functions.) Access these fields as variables named
-with a preceding C<gr_>. Thus, C<$group_obj-E<gt>gid()> corresponds
-to $gr_gid if you import the fields. Array references are available as
-regular array variables, so C<@{ $group_obj-E<gt>members() }> would be
-simply @gr_members.
-
-The getpw() function is a simple front-end that forwards
-a numeric argument to getpwuid() and the rest to getpwnam().
-
-To access this functionality without the core overrides,
-pass the C<use> an empty import list, and then access
-function functions with their full qualified names.
-On the other hand, the built-ins are still available
-via the C<CORE::> pseudo-package.
-
-=head1 NOTE
-
-While this class is currently implemented using the Class::Struct
-module to build a struct-like class, you shouldn't rely upon this.
