Import Debian changes 5e1-1debian/5e1-1

scm (5e1-1) unstable; urgency=low

  * New upstream release.  (Closes: #335970)
  * debian/rules (SCM_OPTIONS): Remove -F turtlegr; the file supporting
    this option seems to have gone by the wayside.
  * debian/rules (binary-arch): Don't try to install grtest.scm; it's gone
    now.
    
  * debian/rules (build-stamp): Use tee to capture output of ./build so
    that we can capture a copy of the file in the build log.
    
  * scm.1: Fix spelling errors in manual page:
     verobse -> verbose; 
     qoutes -> quotes;
     aguments -> arguments;
     neccessary -> necessary;
     preceeds -> precedes.
     syncronization -> synchronization.
     (Closes: #300131)
    
  * debian/postinst, debian/prerm: Assume that install-docs is in the
    standard place, and test for it there with test -x.  (Closes: #292996)
