Misspelling in Doxygen Tutorial

[ReidBix]

"RTF (rich text format) is a file type that can be loaded up into your favorite word processing program. One you have run doxygen, the comments are formatted into a file called doc/rtf/refman.rtf -- try loading up that file. Note that a number of the fields in the file (such as "Title" and "Author") are not yet filled in -- this is addressed below."

The second sentence I assume should say 'Once' rather than 'One'.
