+Experimental bidi presentation
+
+A great portion of the code is brorrowd from texpower bundle:

+
+with modifications to get things working properly in both right to
+left and left to right modes.
+
+For the documentation, please see the texpower bundle documentation.
+Most of the things that work with texpower bundle should also work with
+the bidipresentation class. In addition, a sample presentation (file `sample.tex')
+is provided to give an overview of the presenttaions produced with the
+bidipresentation class.
+
+If you want to report any bugs or typos and corrections in the documentation,
+or ask for any new features, or suggest any improvements, or ask any questions
+about the package, then please do not send any direct email to me; I will not
+answer any direct email. Instead please use the issue tracker:
+  <https://github.com/persian-tex/bidipresentation/issues>
+In doing so, please always explain your issue well enough, always include
+a minimal working example showing the issue, and always choose the appropriate
+label for your query (i.e. if you are reporting any bugs, choose `Bug' label).
