 #          Compression build options          #
 ###############################################
 #
 #
 ############# Building gzip support ###########
 #
 # Gzip support is by default enabled, and the compression type default
 # (COMP_DEFAULT) is gzip.
 #
 # If you don't want/need gzip support then comment out the GZIP SUPPORT line
 # below, and change COMP_DEFAULT to one of the compression types you have
 # selected.
 #
 # Obviously, you must select at least one of the available gzip, lzma, lzo
 # compression types.
 #
 GZIP_SUPPORT = 1

 ########### Building XZ support #############
 #
 # LZMA2 compression.
 #
 # XZ Utils liblzma (http://tukaani.org/xz/) is supported
 #
 # To build using XZ Utils liblzma - install the library and uncomment
 # the XZ_SUPPORT line below.
 #
 #XZ_SUPPORT = 1


 ############ Building LZO support ##############
 #
 # The LZO library (http://www.oberhumer.com/opensource/lzo/) is supported.
 #
 # To build using the LZO library - install the library and uncomment the
 # LZO_SUPPORT line below. If needed, uncomment and set LZO_DIR to the
 # installation prefix.
 #
 #LZO_SUPPORT = 1
 #LZO_DIR = /usr/local


 ########### Building LZ4 support #############
 #
 # Yann Collet's LZ4 tools are supported
 # LZ4 homepage: http://fastcompression.blogspot.com/p/lz4.html
 # LZ4 source repository: http://code.google.com/p/lz4
 #
 # To build configure the tools using cmake to build shared libraries,
 # install and uncomment
 # the LZ4_SUPPORT line below.
 #
 #LZ4_SUPPORT = 1


 ########### Building LZMA support #############
 #
 # LZMA1 compression.
 #
 # LZMA1 compression is deprecated, and the newer and better XZ (LZMA2)
 # compression should be used in preference.
 #
 # Both XZ Utils liblzma (http://tukaani.org/xz/) and LZMA SDK
 # (http://www.7-zip.org/sdk.html) are supported
 #
 # To build using XZ Utils liblzma - install the library and uncomment
 # the LZMA_XZ_SUPPORT line below.
 #
 # To build using the LZMA SDK (4.65 used in development, other versions may
 # work) - download and unpack it, uncomment and set LZMA_DIR to unpacked source,
 # and uncomment the LZMA_SUPPORT line below.
 #
 #LZMA_XZ_SUPPORT = 1
 #LZMA_SUPPORT = 1
 #LZMA_DIR = ../../../../LZMA/lzma465

 # selected to be built

 # support
