+# Tahoe depends upon several libraries (foolscap, twisted, pycryptopp, and
+# others). Left to its own devices, setuptools will look on PyPI for these
+# and will download them at build time. The 'find_links=' entry in setup.cfg
+# causes setuptools to look for these dependent tarballs in tahoe-deps/ and
+# ../tahoe-deps/ before it resorts to downloading them from PyPI.
+
+# http://allmydata.org/source/tahoe/tarballs/tahoe-deps.tar.gz contains a
+# bundle of these dependencies. So it you want to avoid the build-time
+# download (say, if you're on an airplane, or a desert island), just grab a
+# copy and unpack it in your tahoe darcs tree.
+
+# Alternatively, if you're building from a release/nightly tarball instead of
+# a darcs tree, the 'sumo' tarball variant will include all of these
+# dependencies in the tahoe-deps/ directory.
