texexec from parent directory

[Aditya Mahajan <adityam@umich.edu>]

Hi,

  I have the following project structure

base/
   |
   +--project.tex
   |
   +--product.tex
   |
   +--environment.tex
   +
  subdir/
     |
     +---component.tex


If I in subdir and texexec component it compiles fine. If I am in base 
and texexec subdir/component it works fine. However, if I am in the 
parent directory of base and

texexec base/subdir/component

it does not work as the environment file is not found. It seems that 
the search for files is taking place relative to the directory from 
where texexec is invoked, rather than relative to the directory where 
the file resides. Is there some way I can make the component file 
compile from the parent directory of base?

Thanks,
Aditya
