uses relative references to access them. For example, the following
directory structure might be used in the archive:
|-- app.sh
|-- data
| |-- datafile1
| `-- datafile2
|-- logo.jpg
`-- readme.txt
To check the format of the file you create, execute the following
command in Linux. The result should say "gzip compressed data".
file <filename>.tar.gz
3) Put your archive in the "thirdpartydemos" subdirectory of the target
installation directory. This is where the DVSDK software was
installed on the target file system. The default target installation
directory is /opt/dvsdk/dm6446, so the default location for demo
archives is /opt/dvsdk/dm6446/thirdpartydemos. Do not extract the
contents of the archive in this location. Extraction is performed
behind-the-scenes each time the demo is run.
