+Notes on FreeBSD
+----------------
+
+- FreeBSD's default 'make' command doesn't like bup's Makefile. In order to
+ compile the code, run tests and install bup, you need to install GNU Make
+ from the port named 'gmake' and use its executable instead in the commands
+ seen above. (i.e. 'gmake test' runs bup's test suite)
+
+- Python's development headers are automatically installed with the 'python'
+ port so there's no need to install them separately.
+
+- To use the 'bup fuse' command, you need to install the fuse kernel module
+ from the 'fusefs-kmod' port in the 'sysutils' section and the libraries from
+ the port named 'py-fusefs' in the 'devel' section.
+
+- The 'par2' command can be found in the port named 'par2cmdline'.
+
+- In order to compile the documentation, you need pandoc which can be found in
+ the port named 'hs-pandoc' in the 'textproc' section.

+Notes on NetBSD/pkgsrc
+----------------------
+
+ - See pkgsrc/sysutils/bup, which should be the most recent stable
+ release and includes man pages. It also has a reasonable set of
+ dependencies (git, par2, py-fuse-bindings).
+
+ - The "fuse-python" package referred to is hard to locate, and is a
+ separate tarball for the python language binding distributed by the
+ fuse project on sourceforge. It is available as
+ pkgsrc/filesystems/py-fuse-bindings and on NetBSD 5, "bup fuse"
+ works with it.
+
+ - "bup fuse" presents every directory/file as inode 0. The directory
+ traversal code ("fts") in NetBSD's libc will interpret this as a
+ cycle and error out, so "ls -R" and "find" will not work.
+
+ - There is no support for ACLs. If/when some enterprising person
+ fixes this, adjust t/compare-trees.
+
+
+Notes on Cygwin
+---------------
+
+ - There is no support for ACLs. If/when some enterprising person
+ fixes this, adjust t/compare-trees.
+
+ - In t/test.sh, two tests have been disabled. These tests check to
+ see that repeated saves produce identical trees and that an
+ intervening index doesn't change the SHA1. Apparently Cygwin has
+ some unusual behaviors with respect to access times (that probably
+ warrant further investigation). Possibly related:

+Notes on OS X
+-------------
+
+ - There is no support for ACLs. If/when some enterprising person
+ fixes this, adjust t/compare-trees.
