+
+About
+=====
+
+ctools is a software package developed for the scientific analysis of 
+Cherenkov Telescope Array (CTA) data.
+Analysis of data from existing Imaging Air Cherenkov Telescopes (such as 
+H.E.S.S., MAGIC or VERITAS) is also supported, provided that the data and 
+response functions are available in the format defined for CTA.
+
+ctools comprises a set of ftools-like binary executables with a 
+command-line interface allowing for interactive step-wise data analysis. 
+ctools includes also a Python module allowing to control all executables. 
+Creation of shell or Python scripts and pipelines is supported. 
+ctools provides cscripts, which are Python scripts complementing the 
+binary executables. 
+Extensions of the ctools package by user defined binary executables or 
+Python scripts is supported.
+
+ctools are based on GammaLib, a versatile toolbox for the high-level 
+analysis of astronomical gamma-ray data. 
+Besides CTA, GammaLib supports also the analysis of Fermi/LAT and COMPTEL 
+data, and extensions to support further gamma-ray instruments are planned. 
+An interface to virtual observatory ressources is also in preparation. 
+By making use of the GammaLib multi-instrument capabilities, ctools 
+supports the joint analysis of CTA (or any IACT providing data in the 
+CTA format), Fermi/LAT and COMPTEL data.

+
+If you use ctools for work/research presented in a publication we ask you
+that you include the following standard acknowledgment:
+
+   *This research made use of ctools, a community-developed analysis package
+   for Imaging Air Cherenkov Telescope data. ctools is based on GammaLib,
+   a community-developed toolbox for the high-level analysis of astronomical
+   gamma-ray data.*
+
+
+If you wish, you can also include a link to http://cta.irap.omp.eu/ctools/
+(if the journal allows this) in addition to the above text.
+
+If you are giving a presentation or talk featuring work/research that makes
