	1	+Introduction
	2	+============
	3	+
	4	+ctools is a highly modular collection of utilities for processing
	5	+and analysing CTA reconstructed event data in the FITS (Flexible
	6	+Image Transport System) data format. Each utility presents itself
	7	+as a FTOOL (see http://heasarc.gsfc.nasa.gov/ftools/) and performs
	8	+a single simple task such as event binning, event selection or model
	9	+fitting. Individual utilities can easily be chained together in
	10	+scripts to achieve more complex operations, either by using the command
	11	+line interface, or by using the Python scripting language. The ctools
	12	+user interface is controlled by standard IRAF-style parameter files.
	13	+Software is written in C++ to provide portability across most computer
	14	+systems. The data format dependencies between hardware platforms are
	15	+isolated through the cfitsio library package from HEASARC
	16	+(http://heasarc.gsfc.nasa.gov/fitsio/).
	17	+
	18	+This User Manual describes the use of the ctools software.
