# This example will load a file into the fileData object.
# Your application might load fileData from other sources..

# In-place compress the contents of fileData
$success = $gzip.CompressBd($fileData)

# Get the base64 encoded compressed data (in a single line).

# To get the base64 in multiple lines, as it might appear in MIME,
