# INSTALL_CVS - installation instructions and installation script.
#	This version is for use by Mercury developers after you have
#	just checked the files out from the CVS archive. 
#	Note: you need a previous version of Mercury already installed
#	(the CVS archive doesn't have all the necessary files for
#	bootstrapping).
#	You also need autoconf (version 2.58 or later) (and hence GNU m4)
#	installed.
#
# Step 0.  autoconf
#
# Step 1.  ./configure
#
# Step 2.  mmake depend
#
# Step 3.  mmake
#
# Step 4.  tools/bootcheck
#
# Step 5.  cd stage2 && mmake install
#
#	   If you just want to do a `make' rather than a `make install',
#	   then comment out the `mmake install' line below.
#
#	   If you want to install without doing a boot check, then comment
#	   out the `tools/bootcheck' and `cd stage2' lines below.  If the
#	   version of the compiler you checked out is buggy and you don't
#	   perform a boot check first, you risk installing a version of the
#	   compiler incapable of compiling itself.  Make sure you have a
#	   fall-back plan if you do this.
#	   Note also that occasionally changes made to the compiler mean
#	   that installing from a stage 1 build will fail, even when the
#	   compiler is fine.  In such cases the only way to install the
#	   compiler is from the stage 2 directory.
#
#	   If you don't want to do a parallel make, comment out the
#	   `parallel=-j3' line below.
