============================== INTRODUCTION =============================


Ths he goal of this project is to create an UNIX program able to read a CD-ROM 
filesystem, which means to read the content of a .iso file. I should respect 
the ISO 9660 standard available on the Assistants’intranet.
The program  take the path to the file containing the ISO 9660 filesystem as
an argument:


-> ./my_read_iso /tmp/test.iso


================================ USAGE ==================================


TO COMPILE : make
--> this will create the binary file "my_read_iso"
--> my_read_iso [ISO] use the prompt
--> my_read_iso [ISO] < [FILE] read your files and display


TO USE THE TEST SUITE : ./tests/tests.sh [BINARYTESTCOMPARED] [ISO]
--> this will check if the output of the binarytestcompared is the same that the
one made


CAN  BE USE WITH "make check" : make check ARG1=[BINARYTESTCOMPATED]
--> make check ARG1="tests/my_read_iso"
