Execute the following command to rebuild the data for this program:
   tail -n +44 test_read_format_cab.c | /bin/sh
And following works are:
1. Move /tmp/cab/cab.zip to Windows PC
2. Extract cab.zip
3. Open command prompt and change current directory where you extracted cab.zip
4. Execute cab.bat
5. Then you will see that there is a cabinet file, test.cab
6. Move test.cab to posix platform
7. Extract test.cab with this version of bsdtar
8. Execute the following command to make uuencoded files.
 uuencode test_read_format_cab_1.cab test_read_format_cab_1.cab > test_read_format_cab_1.cab.uu
 uuencode test_read_format_cab_2.cab test_read_format_cab_2.cab > test_read_format_cab_2.cab.uu
 uuencode test_read_format_cab_3.cab test_read_format_cab_3.cab > test_read_format_cab_3.cab.uu
