We don't promise that this software works. (But if you find any bugs, 11 please let us know!) 122. You can use this software for whatever you want. You don't have to pay us. 133. You may not pretend that you wrote this software. If you use it in a 14 program, you must acknowledge somewhere in your documentation that 15 you've used the IJG code. 16 17In legalese: 18 19The authors make NO WARRANTY or representation, either express or implied, 20with respect to this software, its quality, accuracy, merchantability, or 21fitness for a particular purpose.

Another support script, install-sh, is copyright by X Consortium 59but is also freely distributable. 60 61The IJG distribution formerly included code to read and write GIF files. 62To avoid entanglement with the Unisys LZW patent (now expired), GIF reading 63support has been removed altogether, and the GIF writer has been simplified 64to produce "uncompressed GIFs". This technique does not use the LZW 65algorithm; the resulting GIF files are larger than usual, but are readable 66by all standard GIF decoders. 67
