+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+This module's default exports override the core \fBgetgrent()\fR, \fBgetgrgid()\fR,
+and \fBgetgrnam()\fR 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 \fIgrp.h\fR;
+namely name, passwd, gid, and members (not mem). The first three
+return scalars, the last an array reference.
+.PP
+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 \f(CW\*(C`gr_\*(C'\fR. Thus, \f(CW\*(C`$group_obj\->gid()\*(C'\fR corresponds
+to \f(CW$gr_gid\fR if you import the fields. Array references are available as
+regular array variables, so \f(CW\*(C`@{ $group_obj\->members() }\*(C'\fR would be
+simply \f(CW@gr_members\fR.
+.PP
+The \fBgetgr()\fR function is a simple front-end that forwards a numeric
+argument to \fBgetgrgid()\fR and the rest to \fBgetgrnam()\fR.
+.PP
+To access this functionality without the core overrides,
+pass the \f(CW\*(C`use\*(C'\fR 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 \f(CW\*(C`CORE::\*(C'\fR pseudo-package.
+.SH NOTE
+.IX Header "NOTE"
+While this class is currently implemented using the Class::Struct
+module to build a struct-like class, you shouldn't rely upon this.
