.\" The code below provides extension macros for the `man' macro package.
.\" Care has been taken to make the code portable; groff extensions are
.\" properly hidden so that all troff implementations can use it without
.\" changes.

.\" With groff, this file is sourced by the `man' macro package itself.
.\" Man page authors who are concerned about portability might add the
.\" used macros directly to the prologue of the man page(s).
.
.
.\" Convention: Auxiliary macros and registers start with `m' followed
.\"             by an uppercase letter or digit.
