 To create a link from one Org file to another, you would use something
-like =[[file:foo.org][The foo]]= or simply =[[file:foo.org]]= (see [[*External 
Links]]).  When
-published, this link becomes a link to =foo.html=.  You can thus
-interlink the pages of your "Org web" project and the links will work
-as expected when you publish them to HTML.  If you also publish the
-Org source file and want to link to it, use an =http= link instead of
-a =file:= link, because =file= links are converted to link to the
-corresponding =.html= file.
