+
+** Summary
+
+~ping_offline.sh~ is a small Bash script meant to indicate when the
+machine it runs on is able to ping a remote server.
+
+** Versions
+| Version | Description             |
+|---------+-------------------------|
+|   0.0.1 | Initial working script. |
+
+** Background
+Sometimes, my machines are on a network that is temporarily
+disconnected for various reasons. I'd like to know approximately when
+they come back online by pinging a remote server; once a successful
+ping is established, I can stop further pings. However, the ~ping~
+executable available (provided by the package ~iputils-ping~) on my
+Pop!_OS 22.04 LTS machine throws an error if the machine is completely
+offline; therefore, I wrote the script to regularly try the command
+until it succeeds at least once.
+
+** Dependencies
+- ~iputils-ping~ package (Version: 3:20211215-1)
