Update of /cvsroot/scsh/scsh-packages/scheme/install-lib
In directory sc8-pr-cvs1:/tmp/cvs-serv10515/scheme/install-lib

Modified Files:
        install-lib.scm 
Log Message:
- added support for package-specific command-line options (this
  implied a complete rewrite of command-line parsing),
- added "--non-shared-only" option, to install only platform-specific
  files,
- changed option "--install-prefix" to "--dest-dir", and modified its
  behaviour so that it now really behaves like DESTDIR,
- changed the meanining of the "lib" location, which must now contain
  one directory per supported platform,
- added (exported) function "get-option-value" which returns the value
  of a command-line options; this subsumes "is-running-dry?" and
  "with-optional-part?", which were consequently removed,
- commented most functions.
