#
# Description:
# ------------
# This is an easily customizable makefile template. The purpose is to
# provide an instant building environment for C/C++ programs.
#
# It searches all the C/C++ source files in the specified directories,
# makes dependencies, compiles and links to form an executable.
#
# Besides its default ability to build C/C++ programs which use only
# standard C/C++ libraries, you can customize the Makefile to build
# those using other libraries. Once done, without any changes you can
# then build programs using the same or less libraries, even if source
# files are renamed, added or removed. Therefore, it is particularly
# convenient to use it to build codes for experimental or study use.
#
# GNU make is expected to use the Makefile. Other versions of makes
# may or may not work.
#
# Usage:
# ------
# 1. Copy the Makefile to your program directory.
# 2. Customize in the "Customizable Section" only if necessary:
#    * to use non-standard C/C++ libraries, set pre-processor or compiler
#      options to <my_cflags> and linker ones to <my_libs>
#      (See Makefile.gtk+-2.0 for an example)
#    * to search sources in more directories, set to <src_dirs>
#    * to specify your favorite program name, set to <program>
# 3. Type make to start building your program.
#
# Make Target:
# ------------
# The Makefile provides the following targets to make:
#   $ make           compile and link
#   $ make NODEP=yes compile and link without generating dependencies
#   $ make objs      compile only (no linking)
#   $ make tags      create tags for Emacs editor
#   $ make ctags     create ctags for VI editor
#   $ make clean     clean objects and the executable file
#   $ make distclean clean objects, the executable and dependencies
#   $ make help      get the usage of the makefile
#   $ make deps      compile only dependencies
#   $ make showcommands  display the commands when compiling

#   Must modified section
#===========================================================================
#   @SRC_DIRS:The directories in which source files reside. Default is '.'.
#   @INC_DIRS:The directories in which header files reside. Default is EMPTY
