It is supposed to be embedded. Could you tell me what
introtest.intro.__doc__ is? The embedding just includes the file
info; for example
sage: Integer.__doc__[0:100]
'File: sage/rings/integer.pyx (starting at line 241)\n\n The \
\class{Integer} class represents arbitr'
That shows where the docstring starts in sage/rings/integer.pyx for
class Integer. There are lots of way that info can be off, or that
Sage can misparse/not find it. It's somewhat fragile.
