# Initializes the bzip library.
#
# bzip can be configured either to use pre-existing binaries
# or to build the library from source.
#
# Options for configuring a prebuilt bzip::
#
#
# The directory containing the bzip binaries.
#
# Overrides the default library name.
#
# The directory containing the bzip headers.
#
# If none of these options is specified, then the environmental
# variables BZIP2_LIBRARY_PATH, BZIP2_NAME, and BZIP2_INCLUDE will
# be used instead.
#
# Options for building bzip from source::
#
#
# The bzip source directory. Defaults to the environmental variable
# BZIP2_SOURCE.
#
# A rule which computes the actual name of the compiled
# libraries based on the build properties. Ignored
# when using precompiled binaries.
#
# The base name to use for the compiled library. Ignored
# when using precompiled binaries.
#
# Examples::
#
# # Find bzip in the default system location
# using bzip2 ;
# # Build bzip from source
# using bzip2 : 1.0.6 : /home/sergey/src/bzip2-1.0.6 ;
# # Find bzip in /usr/local
# using bzip2 : 1.0.6
# : /usr/local/include /usr/local/lib ;
# # Build bzip from source for msvc and find
# # prebuilt binaries for gcc.
# using bzip2 : 1.0.6 : C:/Devel/src/bzip2-1.0.6 : msvc ;
# using bzip2 : 1.0.6 : : gcc ;
