[m-dev.] Proposed installation profiles

[Julien Fischer]

Here are a proposed set of installation profiles as discussed in the "New
release?" thread.

There will be a new option to the configure script, '--enable-install-profile',
that allows users to select an "installation profile", which is a set of library
grades to install.  Below is a proposed set of installation profiles.

Note that:

* LLDS_BASE is the best supported LLDS base grade on the system, as determined
   by the configure script. 
* the default grade for every profile is "hlc.gc".
* the "stseg" component is specified for all low-level C grades (not just
   the debugging and deep profiling ones).
* .mm grades aren't included; we can add a "table" profile if it's thought that
   they should be.


Profile: minimal
Grades:
     - hlc.gc


Profile: base
Grades:
     - hlc.gc
     - hlc.gc.par  (if pthreads is available)
     - LLDS_BASE.gc.stseg
     - LLDS_BASE.gc.par.stseg
     - java        (if Java is available)
     - csharp      (if .NET / Mono is available)
     - erlang      (if OTP is available)


Profile: trail
Grades:
     - all the grades in the "base" profile
     - hlc.gc.trseg
     - LLDS_BASE.gc.stseg.trseg


Profile: debug
GRADES:
     - all the grades from the "base" profile
     - LLDS_BASE.gc.debug.stseg.trseg
     - LLDS_BASE.gc.decldebug.stseg.trseg


Profile: profile
Grades:
     - all the grades from the "base" profile
     - hlc.gc.prof
     - hlc.gc.memprof
     - LLDS_BASE.gc.prof.stseg
     - LLDS_BASE.gc.memprof.stseg
     - LLDS_BASE.gc.profdeep.stseg


Profile: debug-profile
Grades:
     - all the grades from the "base" profile
     - all the grades from the "debug" profile
     - all the grades from the "profile" profile"


Profile: debug-trail
Grades:
     - all the grades from the "base" profile
     - all the grades from the "trail" profile
     - all the grades from the "debug" profile


Profile: profile-trail
Grades:
     - all the grades from the "base" profile
     - all the grades from the "profile" profile
     - all the grades from the "trail profile


Profile: full
Grades:
     - all the grades from the "base" profile
     - all the grades from the "debug" profile
     - all the grades from the "profile" profile
     - all the grades from the "trail" profile


Profile: all
Grades: as above, but with versions of the above for any supported inefficient
LLDS base grades as well (e.g. on a system where LLDS_BASE is 'asm', you would
also get the 'reg' and 'none' versions of *all* the low-level C grades).
