+Graph-tool is an efficient Python module for manipulation and statistical
+analysis of graphs (a.k.a. networks). Contrary to most other python modules
+with similar functionality, the core data structures and algorithms are
+implemented in C++, making extensive use of template metaprogramming, based
+heavily on the Boost Graph Library. This confers it a level of performance that
+is comparable (both in memory usage and computation time) to that of a pure
+C/C++ library.

+The following variables will affect the build process of this package,
+py27-graph-tool-2.27.  Their current value is shown below:
+
+        * JPEG_DEFAULT = jpeg
+        * PYTHON_VERSION_DEFAULT = 27

+        * SSLCERTS = /usr/pkg/etc/openssl/certs
+        * SSLDIR = /usr/pkg/etc/openssl
+        * SSLKEYS = /usr/pkg/etc/openssl/private
+
+Based on these variables, the following variables have been set:
+
+        * JPEGBASE = /usr/pkg
+        * JPEG_TYPE = jpeg
+        * PYPACKAGE = python27
+
+You may want to abort the process now with CTRL-C and change their value
+before continuing.  Be sure to run `/usr/pkg/bin/bmake.bin clean' after
+the changes.
