#  Handles support for BZIP2 compression
#
# ***************************************************************************

# ---------------------------------------------------------------------
# To enable BZIP2 compression, first make sure you have the libbz2.dll
# installed on your system (from: http://sources.redhat.com/bzip2/),
# and then define an environment variable called "BZIP2_DIR" that
# specifies the full path to the directory where it is installed.
# (via the "Advanced" tab of the Control Panel 'System' applet).
#
# Note that the directory you specify should contain the libbz2.dll as
# well as the 'bzlib.h' header file and the 'libbz2.lib' link library.
#
# Note: if the path contains blanks, do NOT surround it with quotes!
# The makefile will do that if it needs to. Just define the variable
# with the path as-is. E.g.:
#
# BZIP2_DIR = E:\MyProjects\bzip2
# ---------------------------------------------------------------------
