+#=== This file includes rules for C programs. ===#
+
+
+# This file is ignored unless _C_STD is defined.
+# _C_STD should be set the the version of C that
+# is used.
+# 
+# If you want to compile with -pedantic, define
+# the variable _PEDANTIC.
+# 
+# Define _CPPFLAGS with any additional CPP
+# flags to use, _CFLAGS with any additional CC
+# flags to use, and _LDFLAGS with any additional
+# LD flags to use.
+# 
+# Defined in path.mk, you can change _ALL_DIRS
+# if you do not want CPP definitions for all
+# directories.
+# 
+# Define _HEADER_DIRLEVELS to specify the directory
+# nesting level in src. It is assumed that all
+# directories contain header files. Set to '0' if
+# there are no header files.
+# 
+# _BIN shall list all commands to build. These
+# should be the basenames. For each command
+# you should be the variable _OBJ_$(COMMAND)
+# that lists all objects files (without the
+# suffix and without the aux/ prefix) that
+# are required to build the command.
+# 
+# Binary you want installed to /sbin rather than
+# /bin shall be listed in _SBIN rather than in
+# _BIN. _SBIN and _BIN may not list binaries
+# with identical names. Analogically, you may
+# add _LIBEXEC for binary to be installed to
+# /libexec.
+# 
+# If you only have one binary, you may select
+# to define _BINDIR to name the variable with
+# the pathname for the directory the binary
+# shall be installed. For example, if you want
+# the binary to be installed to /usr/sbin,
+# define _BINDIR = SBINDIR.
