-# IRIS-ATOMIC
-
-Atomicity related verification based on Iris logic.
-
-## Prerequisites
-
-This version is known to compile with:
-
- - Coq 8.8.2
- - A development version of [Iris](https://gitlab.mpi-sws.org/FP/iris-coq/)
-
-## Building from source
-
-When building from source, we recommend to use opam (1.2.2 or newer) for
-installing the dependencies.  This requires the following two repositories:
-
-    opam repo add coq-released https://coq.inria.fr/opam/released
-    opam repo add iris-dev https://gitlab.mpi-sws.org/FP/opam-dev.git
-
-Once you got opam set up, run `make build-dep` to install the right versions
-of the dependencies.
-
-Run `make -jN` to build the full development, where `N` is the number of your
-CPU cores.
-
-To update, do `git pull`.  After an update, the development may fail to compile
-because of outdated dependencies.  To fix that, please run `opam update`
-followed by `make build-dep`.

-%% Preliminary declarations
-
-%% Options
-
-%% More declarations
-
-%% We use two counters: The global counter is incremented at each reset.
-%% Its value is the ``group'' of a local. 
-%% The local counter is the last numeric value of a bound label in the
-%% current group.  The value of a label #1 is globally set to 
-%% \csname llb@\the\c@llb@global-#1\endcsname
-%% The global command \csname llb@\the\c@llb@global-#1*\endcsname is 
-%% use to ensure that a label is only bound once. Usually a label is
-%% bound and declared at the same time with \llabel. It may also be bound in
-%% advance,  with \lbind, for instance so as to control the numbering.
-%% Then, another \llabel must be used to declare it in the text.
-%% If no \lbind has been used before, the \llabel calls \lbind implicitlt.
