Today I realized that for me it easier to create a small package than to copy a single file.
The example is glabels-schlomo, a Debian package I created just now to store extra gLabels templates for the label sheets that I use at home. The motivation was that I spend half an hour looking through old backups to find a template definition that I had not copied over when I reinstalled my Desktop.
Creating the package took another half an hour and now I can be sure that I won't forget to copy that file again. And I will also have the template definition at work in case I need to print a sheet of labels there.
If you also feel that packaging is better than copying then feel free to use this package as a template for you own stuff. It contains a Makefile and uses git-dch to automatically build a DEB release from the git commits.
