[NTG-context] components and figure search paths

Thanks!

Is the idea to use \currentcomponentpath in the directory={...}?  I put
those three \defs into core-job.tex and remade the formats (cont-en:
ver: 2006.04.17 23:14 fmt: 2006.5.10).  But I couldn't figure out quite
how to use it.  The abc-1.eps figure, referred to in the component and
living in its directory, isn't found automatically though maybe I need
to use \currentcomponentpath explicitly?

[Meanwhile I'm using a workaround that Mojca suggested offlist: by hand
put the relative component path in the directory={...}, which is mostly
fine as I don't change the relative directory structure as much as I
change the root.]

But back to \currentcomponentpath.  I put \show\currentcomponentpath in
the component chap/1/c_ch1.tex to see what was going on.  If I
understand right, your intention is that \currentcomponentpath would be
chap/1 inside chap/1/c_ch1.tex.  But it ends up as "..".  Here are the
relevant lines from the texexec log:

$ texexec onebook
systems         : begin file onebook at line 1
systems         : begin file project_books at line 2
(./project_books.tex
systems         : begin file env_books at line 3
(./env_books.tex)
systems         : end file env_books at line 3
)
systems         : end file project_books at line 2
systems         : begin file chap/1/c_ch1 at line 3
(./chap/1/c_ch1.tex
> \currentcomponentpath=macro:
->..
l.3 \show\currentcomponentpath
                              
? 
figures         : figure abc-1 can not be found
floatblocks     : 1 placed
)
systems         : end file chap/1/c_ch1 at line 3
[1.1]
systems         : end file onebook at line 4
 )

And here is a .tgz file with all of these files in this structure:

./chap/1/abc-1.eps
./chap/1/c_ch1.tex
./project_books.tex
./env_books.tex
./onebook.tex
