Most notably, not all FSLs are compatible with the GNU General Public License (GPL), which also is a FSL. Software licenses are distinguished whether they are closed source or open source licenses, free or unfree, and enforce copyright or copyleft (the GPL are/does the latter, respectively). Also, patent issues have to be considered: Some free software licenses, like the Apache License, include stipulations that the grated patent license is void if the licensee sues the licenser for patent infringement; other licenses do not. A quick Google search shows: - NumPy is licensed under the “BSD-new license”. <https://en.wikipedia.org/wiki/NumPy> - PyDAQmx can be licensed under either ,-<https://github.com/clade/PyDAQmx/blob/master/README> | | (1) The BSD license. | (2) Any other license, as long as it is obtained from the original | author. - PyVISA is licensed under “The MIT License” (X11 License) <https://github.com/hgrecco/pyvisa/blob/master/LICENSE> See also: <https://en.wikipedia.org/wiki/Comparison_of_free_and_open-source_software_licenses> <http://www.gnu.org/licenses/license-recommendations.html> IANAL. -- PointedEars Twitter: @PointedEars2 Please do not cc me. / Bitte keine Kopien per E-Mail. -- https://mail.python.org/mailman/listinfo/python-list
