I cannot find the harmonics source file by using the provided
Source.

I found the licence of the file, and it seems that it isn't free
data like free software (no selling):
http://www.flaterco.com/xtide/harmonics_boilerplate.txt

I don't know exactly how to deal with this issue. First the issue of
mixing with xtide. It may be legal to distribute it together with 
GPLed programs if the GPL don't apply to data, only to software, and 
if it isn't the case, it would be possible to put the harmonics file 
in a separate package. I personnally think that it would be better to 
put the harmonics file in a separate src.rpm if the licence is really 
for non commercial use only.

That kind of data may be legally redistributed by fedora, however
it will be troublesome if somebody sells fedora. So they definitively
cannot be packaged as-is. It seems to me that the best thing to do 
would be to add a README/something in the description in the packages 
needing the harmonics file and provide a shell script which does a 
wget on the file, run the tcd-util conversion on it and install, 
or alternatively download directly the .tcd file.



The wvs file should be used (provided the licence is acceptable for
fedora). I couldn't find the licence at the url provided at the xtide 
page. Maybe ask upstream or the NOAA?

>From reading of the code, one can set the WVS_DIR variable to
the directory holding the wvs data files, or it may be listed in 
xtide.conf. 

It seems to me that WVS_DIR must be set for tideEditor.
