adverbio - I/O redirection with adverbial commands

Rationale

  "Adverbial" commands are shell commands which re-exec their command
  line directly, usually after making some change to their
  environment.

  Well-known examples are "nice" and "nohup".  Sometimes however the
  change the command makes interacts inconveniently with the shell's
  I/O redirection: if the change could affect the effect of such
  redirections, then you might want them to take place after the
  change rather than before.  adverbio provides a convenient way to
  achieve this.
  
  Consider, for example, the command "really", which executes its
  arguments as root.  If you want to redirect the output of such a
  command then the naive approach:
  
    really ls > /root/file
  
  does not work - the mortal user's shell tries to perform the
  redirection, and this fails.  It is necessary to reinvoke the shell
  to get it to perform the redirection at the right point:
  
    really sh -c 'ls > /root/file'
  
  However this is unacceptable for general use, as it requires shell
  commands to be shell-quoted - and so any argument strings must be
  quoted twice!  This is messy and error prone.
  
  With adverbio the above becomes:
  
    really adverbio -o /root/file -- ls
  
  which is slightly verbose, but requires no quoting.

Installation

  sh ./configure
  make
  make install              (as root)

  See "INSTALL" for generic installation instructions.
