 Many "modern" Windows programs have a feature (some would say annoyance) of
 presenting the user tips at program startup. While this is probably useless to
 the advanced users of the program, the experience shows that the tips may be
 quite helpful for the novices and so more and more programs now do this.

+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.
