+# RabbitMQ TCL
+
+This library is a wrapper around [rabbitmq-c](https://github.com/alanxz/rabbitmq-c).
+
+It exposes the C functions allowing to interact with a RabbitMQ server in TCL.
+
+## Documentation
+
+* rabbitmq-tcl.c - the extension code
+* makePkgIndex.c - a tool to prepare pkgIndex.tcl
+
+## Customize the build
+
+### config.h
+
+If you want to be able to use different default values, you can edit the defines
+at `src/config.h`, then rebuild the extension.
+
+### E4C
+
+This extension is a wrapper around librabbitmq, which is not bulletproof against
+null pointer errors.
+
+In a critical context, we suggest to enable e4c. If a command `mq quux` would
+try to use a NULL pointer, instead of segfault, you would get a TCL error,
+and then would be able to resume operations:
+
+```
+% mq quux
+Segmentation violation.
+%
+```

+
+### Note if you relicense a derivative work
+
+If you create any derivative work of this library, you must do one of the
+following actions:
+
+ * drop exceptions4c support (rm vendor/e4c and the #ifdef USE_E4C blocks)
+ * release the whole work under LGPLv3 or GPLv3
+ * publish source code or object form (.o) so it's possible to relink
+ against another version of exceptions4c [this is what we do]
+
+According http://www.gnu.org/licenses/gpl-faq.html#LGPLStaticVsDynamic, you can
+link staticly against a LGPL library as long as you provide the .o object of
+your application stripped of the LGPL code or provide the source code and build
+tools to achieve it.

+### Acknowledgment

+ which is used as the model and starting point for this library.
+
+### Colophon
+
+This work has been created for Nasqueron, to allow their operations and
+infrastructure TCL code to interact to our message broker.
