Easier to install in alternate places, without the extra 'usr/' in paths.
Default is still /usr, but setting DESTDIR=/usr/local should work.
Also replace hard-coded directory with variable.
- changed version number to 2.5.0 in main help page.
- changed OH7AN to OK2CQR in all help pages as understood from your web pages "OK2CQR is back" that you returned to your old callsign.
- went through https://github.com/ok2cqr/cqrlog/commits/master and added some lines to CHANGELOG. I'm still sure that not all things are in the list.
Perhaps it would be good idea to add a changelog line as the first line of pull request text. Then it would be easier to collect them afterwards.
This is not complete list. I would be happy to see more additions or fixes to current CHANGELOG also from others!
