I have translated into spanish the document IntroNV.lyx.
For anyone who is interested in, it's available as a link
at:
http://wiki.lyx.org/LyX/Manuals
A small bug for me: either the original version or my
translation, the bookmarks in pdflatex shows the word LyX
as "L.25emYX", however the word LaTeX is OK.
I don't know fix it.
Also, I have put the \pagenumbering{Roman} instead of
{roman},
for TOC in the preamble, because some problem that has to
do
with the babel package spanish.ldf; the pdflatex output
give
error if {roman}.
And also I have changed \clearpage for \cleardoublepage.
Thanks to LyX Team, regards,
Ignacio García
