+When 'xpg_echo' bash shell option is unset (usually the default)
+echo builtin does not expand backslash-escape sequences by default
+(i.e. '\n' is echoed as '\n' instead of newline). Not all bash
+installations have this feature we depend on activated by default.
+
+Note that the feature is bash (and GNU /bin/echo) specific. It is used
+as it is convenient. If portability is needed (elsewhere) use printf(1)
+(also often available as a shell builtin).
