LENSTOOL package contains a C library and several executables for creating, and post-processing gravitational lensing models. LENSTOOL lens model, processing steps, and input data are listed in an ASCII parameter file. The lenstool executable parses this file and performs the successive requested processing steps. Perl scripts provided in the package allow to visualize output results in the graphical interface DS9 provided by Smithsonian Astrophysical Observatory (SAO). In case of MCMC model optimization, MCMC samples are delivered in an output ASCII file. MCMC samples can be post-processed by several additional executables provided in the package.
