+?RCS: $Log: Init.U,v $
+?RCS: Revision 1994/10/31 09:45:59 ram
+?RCS: patch44: removed Options from MAKE to prevent Init overrides
+?RCS: patch44: option processing now done after Myinit thanks to new Begin.U
+?RCS: patch44: moved "Beginning of configuration questions" to Begin.U
+?RCS: patch44: moved signal trapping instruction to Begin.U as well
+?RCS: Revision 3.0 1993/08/18 12:05:02 ram
+?RCS: Baseline for dist 3.0 netwide release.
+?X: This file initializes certain default variables used by Configure. They
+?X: may be overridden or added to by definitions in Myinit.U.
+?MAKE:Init eunicefix _exe: Null
+?MAKE: -pick add $@ %<
+?MAKE: -pick weed $@ ./Init
+?S: When running under Eunice this variable contains a command which will
+?S: convert a shell script to the proper form of text file for it to be
+?S: executable by the shell. On other systems it is a no-op.
+?S:_exe (exe_ext):
+?S: This variable defines the extension used for executable files.
+?S: For unix it is empty. Other possible values include '.exe'.
+?S: DJGPP, Cygwin and OS/2 use '.exe'. Stratus VOS uses '.pm'.
+?S: On operating systems which do not require a specific extension
+?S: for executable files, this variable is empty.
+?V:define undef smallmach:rmlist
+?X: Throughout the units, one may make use of $define and $undef to reference
+?X: a defined symbol or an undefined one. There is no need to add them in
+?X: the dependency line since this unit makes them visible via ?V:, and
+?X: everyone inherits from those symbols since by convention Init.U is the
+?X: root dependency.
+: Initialize wide constants
