Ports using USE_PYTHON=distutils are now flavored. They will
automatically get flavors (py27, py34, py35, py36) depending on what
versions they support.
There is also a USE_PYTHON=flavors for ports that do not use distutils
but need FLAVORS to be set. A USE_PYTHON=noflavors can be set if
using distutils but flavors are not wanted.
A new USE_PYTHON=optsuffix that will add PYTHON_PKGNAMESUFFIX has been
added to cope with Python ports that did not have the Python
PKGNAMEPREFIX but are flavored.
USES=python now also exports a PY_FLAVOR variable that contains the
current python flavor. It can be used in dependency lines when the
port itself is not python flavored. For example, deskutils/calibre.
By default, all the flavors are generated. To only generate flavors
for the versions in PYTHON2_DEFAULT and PYTHON3_DEFAULT, define
BUILD_DEFAULT_PYTHON_FLAVORS in your make.conf.
In all the ports with Python dependencies, the *_DEPENDS entries MUST
end with the flavor so that the framework knows which to build/use.
This is done by appending '@${PY_FLAVOR}' after the origin (or
@${FLAVOR} if in a Python module with Python flavors, as the content
will be the same). For example:
RUN_DEPENDS= ${PYTHON_PKGNAMEPREFIX}six>0:devel/py-six@${PY_FLAVOR}

implementation of genome scale analyses. The library contains a variety of
useful modules, but the particular strengths are:
Classes for reading and working with genome-scale multiple local alignments
(in MAF, AXT, and LAV formats). Generic data structure for indexing on disk
files that contain blocks of data associated with intervals on various
sequences (used, for example, to provide random access to individual
alignments in huge files; optomized for use over network filesystems).
Data structures for working with intervals on sequences:
* "Binned bitsets" which act just like chromosome sized bit arrays,
but lazily allocate regions and allow large blocks of all set or
all unset bits to be stored compactly
* "Intersecter" for performing fast intersection tests that preserve
both query and target intervals and associated annotation
