+# Function getOS
+#
+# Getting the OS is not the same on all distributions.  First, we use
+# uname to find out if we are running on Linux or FreeBSD. For all the
+# supported versions of Debian and Ubuntu, we expect to find the
+# /etc/os-release file which has multiple lines with name-value pairs
+# from which we can get the OS name and version. For RedHat and its
+# variants, the os-release file may or may not exist, depending on the
+# version.  If it doesn't, then we look for the release package and
+# get the OS and version from the package name. For FreeBSD, we use the
+# "uname -rs" command.
+#
+# A string is written to stdout with three values separated by ":":
+#    OS
+#    OS Name
+#    OS Version
+#
+# If none of these files was found, an empty string is written.
+#
+# Return: 0 for success, 1 for error
