.\" 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.
.
.\" Setting the `mG` register to a positive value (e.g., on the command
.\" line) enables usage of macros defined here that have alternative
.\" definitions in the main groff man macro file. This is for testing.
.\" The logic uses subtraction due to frustrating, AT&T troff-compatible
.\" limitations on the '!' operator.
.
.
.\" Protect against being sourced twice.

. nx

.\" Define this to your implementation's constant-width typeface.
.ds mC CW
.if n .ds mC R
.
.\" Save the automatic hyphenation mode.
.\"
.\" In AT&T troff, there was no register exposing the hyphenation mode,
.\" and no way to save and restore it. Set `mH` to a reasonable value
.\" for your implementation and preference.
