+In a tips.txt file, lines that begin with a \# character are considered comments 
+and are automatically skipped. Blank lines and lines only having spaces are also 
+skipped.

+You can easily add runtime-translation capacity by placing each line of the 
+tips.txt file inside the usual translation macro. For example, your tips.txt 
+file would look like this:
+
+\begin{verbatim}
+_("This is my first tip")
+_("This is my second tip")
+\end{verbatim}
+
+Now add your tips.txt file into the list of files that gettext searches 
+for translatable strings. The tips will thus get included into your 
+generated .po file catalog and be translated at runtime along with the rest of 
+your application's translatable strings. 
+Note1: Each line in the tips.txt file needs to strictly begin with exactly the 
+3 characters of underscore-parenthesis-doublequote, and end with 
+doublequote-parenthesis, as shown above. 
+Note2: Remember to escape any doublequote characters within the tip string with
+a backslash-doublequote.
