# 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.
