/*
* NAME
* c - the C compiler cookbook
*
* DESCRIPTION
* This cookbook describes how to work with C files.
* Include file dependencies are automatically determined.
*
* RECIPES
* %.o: %.c make object files form C source files
* %.ln: %.c make lint object files from C source files
*
* VARIABLES
* c_incl The C indude dependency sniffer command.
* Not altered if already defined.
* cc The C compiler command
* Not altered if already defined.
* lint The lint command.
* Not altered if already defined.
* cc_flags options to pass to the C compiler command
* Not altered if already defined.
* The default is "-O".
* cc_include_flags Options passed to the C compiler and c_incl
* controlling include file searching.
* Not altered if already defined.
* The default is empty.
* cc_src C source files in the current directory.
* dot_src Source files constructable in the current directory
* (unioned with existing setting, if necessary).
* dot_obj Object files constructable in the current directory
* (unioned with existing setting, if necessary).
* dot_clean Files which may be removed from the current directory
* in a clean target.
* dot_lint_obj Lint object files constructable in the current directory
* (unioned with existing setting, if necessary).
*
* SEE ALSO
* program The program cookbook:
* ld The linker program
* ld_flags The linker flags, NOT libraries
* ld_libraries The linker flags (-L, -l) for libraries
*
* MANIFEST: cookbook for using C
