NAME
       User::pwent - by-name interface to Perl's built-in
       getpw*() functions

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);


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 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 pw_ in front their method names.  Thus,
       $passwd_obj->shell() corresponds to $pw_shell if you
       import the fields.

       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 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
       CORE:: pseudo-package.

NOTE
       While this class is currently implemented using the
       Class::Struct module to build a struct-like class, you
       shouldn't rely upon this.
