+Universal strace wrapper for debugging
+======================================
+
+stracify is a universal strace wrapper for debugging purposes. It replaces
+an arbitrary binary with itself, ensuring it will be called as close to the
+original as possible, and also includes some management code to wrap or
+unwrap binaries.
+
+Installation
+============
+
+Install mksh as a dependency, then install the stracify script into the
+PATH.
+
+Wrapping a binary
+=================
+
+Wrapping a binary is done using the command `sudo stracify /usr/bin/foo`.
+
+An optional strace filter expression can be passed, like `sudo stracify
+/usr/bin/foo open,write`.
+
+On Debian systems, care is taken to register the diversion with dpkg.
+
+Finding the strace output of calls
+==================================
+
+The output fiels are stored in a directory structure organised like this:
+
+```
+/var/log/stracify/
+ |- usr_bin_foo/
+     |- root/
+         |- strace_2017-09-08T14:19:57+02:00_11911.log.11924
+     |- user1/
+         |- ...
+```
+
+This structure was chosen so all users can run the wrapped binary, but
+without opening up the strace outputs from one user's calls to others. The
+template for the log file names is `strace_$date_$pif.$childpid`.
+
+Please note that due to the architecture of stracify, the logs will contain
+quite a bit of trace from stracify and mksh themselves. This is not very
+pretty, but better than losing functionality in the wrapped binary due to a
+crooked call.
+
+Unwrapping a binary
+===================
+
+A binary can be unwrapped using the command `stracify unwrap /usr/bin/foo`.
