However, Gradint's use +of eSpeak may be a 'borderline' case, as may be the Windows version's +use of py2exe, so I feel the safest thing is to make Gradint GPL too. + +I could make a more liberally licensed version of the Gradint core +code without the parts that drive eSpeak etc. This liberally-licensed +core code would then be includeable in the whole GPL version and also +in other non-GPL projects. To keep things simple, I have not made +such a division by default (the Gradint GUI displays "GPL" because +it's usually associated with eSpeak, and to save screen space I don't +want to change that to "whole thing's GPL but some parts are Apache"), +but contact me if you need me to make or approve a cut-down version of +the code containing just the parts that don't have to be GPL, probably +as a separate project. + +The GPL allows commercial use, and it does not allow the removal of +any permissions it grants, including the permission for commercial +use. Therefore, it is NOT allowed to take a GPL program together with +a program that's distributed under a "non-commercial use only" license +and distribute the combined version, unless it falls under the GPL's +provision of "mere aggregation". (I could give special permission, +but my permission would not be valid if the above "borderline" cases +really do mean that Gradint must be GPL with no extra permissions.) + +The RISC OS distribution of Gradint includes PlayIt, which is licensed +for non-commercial use only. Since Gradint's use of PlayIt is +optional, and it is run as an independent system command with a very +simple command line (no complex exchange of data structures etc), I +believe this should qualify as "mere aggregation". + +The Windows and Mac versions of Gradint include not only eSpeak but +also some customised dictionary files, one of which contains +pronunciation data derived from the OALD with a "non-commercial only" +license. Since eSpeak's dictionary is a user-customisable file loaded +at runtime, and does not make up part of eSpeak's code proper, it is +arguable that making a non-commercial download of eSpeak + OALD is +"mere aggregation" allowed by the GPL. However, there is also the +issue that this modified dictionary was derived not only from the OALD +but also from eSpeak's original data files, including en_rules which +is explicitly GPL, so I would need special permission to combine this +with OALD in a non-commercial binary (otherwise I would have to ship +the files separately and have eSpeak combine them at runtime). +Thankfully though, I do indeed have special permission, because I +collaborated with eSpeak's original author Jonathan Duddington (to +help improve eSpeak's English, Mandarin and Ancient Greek voices and +port it to Mac and PocketPC), and he was happy for my pre-compiled +"non-commercial only" combination to go into Gradint's downloads. + +This does however mean these Mac and Windows bundles cannot be +upgraded to eSpeak-NG, since the special permission I received from +Jonathan to make a "non-commercial" OALD-integrated download applies +only to my use of his original eSpeak data: the eSpeak-NG contributors +were not informed. Anyway, my process for adding OALD entries to the +eSpeak data has not been as thoroughly tested on recent versions of +the eSpeak-NG data. Gradint can however work with eSpeak-NG if you +supply it separately, and it is possible that eSpeak-NG's improvements +in its default data have reduced the need for OALD data anyway, +although I'm still choosing to ship old-eSpeak plus OALD in my +Mac and Windows 'bundle' downloads. + +windows/ contains a copy of ptts.exe extracted from Jampal from +jampal.sourceforge.net with is GPL, and madplay.exe (I can't remember +how I got this binary but I know madplay is GPL), and now LAME. + +qtplay is used by Gradint on OS X 10.4, which lacks afplay. +We bundle qtplay with the Mac version, and it has a BSD-like license +(see qtplay.copyright for details). + +Mac and Windows additionally ship SOX which is GPL. + +To save on server space, I have not included the source code to the +third-party free software binaries I ship.
