    initial v1  
    11There is now LASzip packaging, see:

    3  * [http://anonscm.debian.org/cgit/pkg-grass/laszip.git git repository for the laszip package]

    55Unfortunately the LASzip source uses a modified copy of the FastAC ([http://www.cipr.rpi.edu/research/SPIHT/EW_Code/FastAC_Readme.pdf Readme], [http://www.cipr.rpi.edu/research/SPIHT/EW_Code/FastAC.zip Source]) algorithm whose license doesn't allow modification making it incompatible with the LGPL-2.1 license used by LASzip. See the thread started by the Debian FTP master feedback:

    9 I've contacted the FastAC authors asking them to consider relicensing the code, Amir Said replied that he would be glad to see it used in Free Software projects and asked what they needed to do. I've recommended using the [http://spdx.org/licenses/BSD-2-Clause BSD-2-Clause] license which is close to the currently license of FastAC and most widely compatible with other Free Software licenses.

    1111It has been very quiet ever since. I'll contact the libLAS & LASzip authors to restart the discussion around the troublesome FastAC code to hopefully get this issue resolved.
