public class InputStreamProvider
extends Object
```
A class that provides an InputStream from a File. The file can be compressed or uncompressed. Currently supported compressions:
- Gzip (extension .gz)
- Zip (extension .zip) in this case a stream to the first entry in the zip file is returned
- Jar (extension .jar) same as .Zip; only stream to first entry is returned
- Z (extension .Z) compressed using the unix compress command
- for any other extension, no compression is assumed
