$(basename $0) - prepare to build t2h under iOS/MacOSX/BSD/Lunix/Unix-like platforms.
            In case of succeed script return 0, in case of failure 1(for details see the ${LOG_FILE})

Usage: $(basename $0) [OPTIONS] ...

Defaults for the options are specified in brackets.

Options:
   --help, -h                 display usage and exit 

   --shared=[yes|no]          create an shared core library [detauld=Yes]
 
   --enable-int-workaraund    on int workaraund 

   --build-type=[D|R|R]       set build type [default=Debug]
	                         
                              Debug 
                              - generate debug build
                              
                              Release
                              - generate release build

                              - generate release with debug info

   --clear, -c                clear all previously builds 

Evnt. variables:

   BOOST_ROOT [OPTIONAL] 
     
     This variable need to the build system(CMake) to find Boost headers & libraries.   
     If Boost already into PATH then not need to set BOOST_ROOT. 
   
   LIBTORRENT_ROOT [REQUIRED] 
  
     This variable need to the build system to find headers & libraries.

Example:
  	
   export BOOST_ROOT=/home/boost_XXX
   export LIBTORRENT_ROOT=/hone/liborrent_XXX
   ./$(basename $0) --clear --build-type=Release
