Popis:	The nature of dark matter (DM) is still an open question in Physics. Gamma-ray and neutrino telescopes have been searching for DM signatures for several years and no detection has been obtained so far. In their quest, these telescopes have gathered a wealth of observations that, if properly combined and analyzed, can improve on the constraints to the nature of DM set by individual instruments. In this contribution, we present two open-source analysis tools aimed at performing the before mentioned combined analysis: gLike, a general-purpose ROOT-based code framework for the numerical maximization of joint likelihood functions, and LklCom, a Python-based tool combining likelihoods from different instruments to produce combined exclusion limits on the DM annihilation cross-section. Comment: 4 pages, 3 figures, to appear in the proceedings of the XXXI Astronomical Data Analysis Software and Systems (ADASS) conference (published by ASP)
