variable. This is done in the preferences, much like as the PATH prefix.
A single '.' in the paths will get replaced with the current document dir
and also non-absolute paths will be prefixed with that dir.
The default semantics of TEXINPUTS apply, such that, for example, if a
path is terminated with a double slash, all subdirectories will be also
searched by both the TeX engine and ancillary programs such as dvi
previewers or dvips. As an example, if the prefix is set to ".:figs", the
TEXINPUTS variable will be set as ".:<docdir>:<docdir>/figs:$ORIGTEXINPUTS",
where <docdir> is the document directory.
The initial '.' is necessary to address the actual current dir (this will
be the temp dir at preview time), while if TEXINPUTS was initially unset,
such that $ORIGTEXINPUTS is empty, a colon (or semicolon on Windows) will
end the path list. This is very important, because we don't want to replace
the system directories but to complement them and, in order to do that, an
empty element has to be present in the list. Indeed, according to the
TEXINPUTS semantics, an empty element means the standard search path.
This works whether TEXINPUTS is originally set or not, because if the
original TEXINPUTS starts with a colon (meaning that the standard search
path is wanted there) we will have an empty element at that point,
otherwise the final colon will simply serve as a path separator.
Of course, on Windows a ';' has to be used as a path separator. LyX will
take care of transforming the platform path list into one understandable
by the TeX engine. For example, this will be the case for a Cygwin version
of LyX using a native Windows TeX engine or viceversa. I tested all of
this and it works for me.

Sorry Peter, but this was breaking too many things, see discussions
