+# Initializes the libjpeg library.
+#
+# libjpeg can be configured either to use pre-existing binaries
+# or to build the library from source.
+#
+# Options for configuring a prebuilt libjpeg::
+#
+#   <search>
+#       The directory containing the libjpeg binaries.
+#   <name>
+#       Overrides the default library name.
+#   <include>
+#       The directory containing the libjpeg headers.
+#
+# If none of these options is specified, then the environmental
+# variables LIBJPEG_LIBRARY_PATH, LIBJPEG_NAME, and LIBJPEG_INCLUDE will
+# be used instead.
+#
+# Options for building libjpeg from source::
+#
+#   <source>
+#       The libjpeg source directory.  Defaults to the environmental variable
+#       LIBJPEG_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 libjpeg in the default system location
+#   using libjpeg ;
+#   # Build libjpeg from source
+#   using libjpeg : 8c : <source>/home/steven/libjpeg-8c ;
+#   # Find libjpeg in /usr/local
+#   using libjpeg : 8c
+#     : <include>/usr/local/include <search>/usr/local/lib ;
+#   # Build libjpeg from source for msvc and find
+#   # prebuilt binaries for gcc.
+#   using libjpeg : 8c : <source>C:/Devel/src/libjpeg-8c : <toolset>msvc ;
+#   using libjpeg : 8c : : <toolset>gcc ;
