# Initializes the libtiff library.
#
# libtiff can be configured either to use pre-existing binaries
# or to build the library from source.
#
# Options for configuring a prebuilt libtiff::
#
# <search>
# The directory containing the libtiff binaries.
# <name>
# Overrides the default library name.
# <include>
# The directory containing the libtiff headers.
#
# If none of these options is specified, then the environmental
# variables LIBTIFF_LIBRARY_PATH, LIBTIFF_NAME, and LIBTIFF_INCLUDE will
# be used instead.
#
# Options for building libtiff from source::
#
# <source>
# The libtiff source directory. Defaults to the environmental variable
# LIBTIFF_SOURCE.
# <tag>
# A rule which computes the actual name of the compiled
# libraries based on the build properties. Ignored
# when using precompiled binaries.
# <build-name>
# The base name to use for the compiled library. Ignored
# when using precompiled binaries.
#
# Examples::
#
# # Find libtiff in the default system location
# using libtiff ;
# # Build libtiff from source
# using libtiff : 4.0.1 : <source>/home/steven/libtiff-4.0.1 ;
# # Find libtiff in /usr/local
# using libtiff : 4.0.1
# : <include>/usr/local/include <search>/usr/local/lib ;
# # Build libtiff from source for msvc and find
# # prebuilt binaries for gcc.
# using libtiff : 4.0.1 : <source>C:/Devel/src/libtiff-4.0.1 : <toolset>msvc ;
# using libtiff : 4.0.1 : : <toolset>gcc ;
#
