# NAME
#	makedefs 1
# SUMMARY
#	makefile configuration utility
# SYNOPSIS
#	\fBmakedefs\fR
# DESCRIPTION
#	The \fBmakedefs\fR command identifies the program compilation
#	environment, and emits macro definitions on the standard output
#	stream that can be prepended to template Makefiles.
#
#	Default settings can be overruled by specifying them as
#	environment variables. Use quotes if variables contain
#	whitespace or shell meta characters.
# .IP \fBAUXLIBS=\fIobject_library...\fR
#	Specifies one or more non-default object libraries.
# .IP \fBCC=\fIcompiler_command\fR
#	Specifies a non-default compiler. On many systems, the default
#	is \fBgcc\fR.
# .IP \fBCCARGS=\fIcompiler_arguments\fR
#	Specifies non-default compiler arguments, for example, a non-default
#	\fIinclude\fR directory.
# .IP \fBDEBUG=\fIdebug_level\fR
#	Specifies a non-default debugging level. The default is \fB-g\fR.
#	Specify \fBDEBUG=\fR to turn off debugging.
# .IP \fBOPT=\fIoptimization_level\fR
#	Specifies a non-default optimization level. The default is \fB-O\fR.
#	Specify \fBOPT=\fR to turn off optimization.
