 +=====grabit=====
 +There is a grabit for this project, which will provide you with some files pertinent for performing this project.
 +
 +Run '**grabit**' on lab46 in the appropriate manner to obtain the files.
 +
 +=====Compiling=====
 +Since there is a provided Makefile in the project grabit, we can use that to compile, either regularly:
 +
 +<cli>
 +yourpi:~/src/cprog/cnv0$ make
 +</cli>
 +
 +Or, with debugging support:
 +
 +<cli>
 +yourpi:~/src/cprog/cnv0$ make debug
 +</cli>

-=====Compiling===== 
-As we have been doing all along, use the following options to gcc when compiling: 
- 
-<cli> 
-lab46:~/src/c4eng/cnv0$ gcc -Wall --std=gnu99 -o cnv0 cnv0.c 
-lab46:~/src/c4eng/cnv0$
