+# Yaroslav de la Peña Smirnov 2021
+# Shortcut script for backing up files with rsync.
+# By default it starts a dry run, to check that there are no conflicts. To
+# commit the copy, i.e. do a normal (non-dry) run, use -c as the first or last
+# argument.

+############################# Config example ###################################
+## Lines in the locations file contain the shortcuts for the sources and
+## destinations. For example, sources:
+# src	d	/home/yaroslav/docs
+# src	m	/home/yaroslav/music
+## destinations:
+# dst	rm	yaroslav@example.com:
+# dst	hd	/mnt/disk/
+## The columns MUST be separated by ONE tab character
