      Here all the files from different TeX-related 
      packages are collected in one directory. Of 
      course, mktexlsr is called. Later placed 
      directories take precedence. It is supposed that
      share and libexec are symlinked, and bin is
      recreated with wrappers for libexec-located 
      linked binaries.
