#  The .bz2 file format is not an archive.  Only a single
#  file may be compressed / decompressed.  It is for this reason that you'll
#  often see TAR files compressed with BZip2 (i.e. a file
#  ending in .tar.bz2.

#  This example will uncompress an XML file.
#  The 1st arg is the file to decompress, the 2nd arg is
#  the output filename.
