+=head1 NAME
+
+User::pwent.pm - by-name interface to Perl's built-in getpw*() functions
+
+=head1 SYNOPSIS
+
+ use User::pwent;
+ $pw = getpwnam('daemon') or die "No daemon user";
+ if ( $pw->uid == 1 && $pw->dir =~ m#^/(bin|tmp)?$# ) {
+     print "gid 1 on root dir";
+ } 
+
+ use User::pwent qw(:FIELDS);
+ getpwnam('daemon') or die "No daemon user";
+ if ( $pw_uid == 1 && $pw_dir =~ m#^/(bin|tmp)?$# ) {
+     print "gid 1 on root dir";
+ } 
+
+ $pw = getpw($whoever);
+
+=head1 DESCRIPTION
+
+This module's default exports override the core getpwent(), getpwuid(),
+and getpwnam() functions, replacing them with versions that return
+"User::pwent" objects.  This object has methods that return the similarly
+named structure field name from the C's passwd structure from F<pwd.h>; 
+namely name, passwd, uid, gid, quota, comment, gecos, dir, and shell.
+
+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<pw_> in front their method names.
+Thus, C<$passwd_obj-E<gt>shell()> corresponds to $pw_shell if you import
+the fields.
+
+The getpw() funtion 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::Template
+module to build a struct-like class, you shouldn't rely upon this.
