The R Project SVN R

These files are shell and perl scripts used for configuring/building R.
They are not required at run time, and hence not installed.

The files are as follows.

  config.guess
  config.sub
    auxiliary scripts for configure.
    From https://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess;hb=HEAD etc

  config.rpath
    from gettext 1.18.1.1 sources.  Modified here to allow for FreeBSD 10.x.

  install-sh
  mdate-sh
  missing
    standard tools from GNU autoconf.  Taken from the autoconf CVS
    (pserver:anoncvs@subversions.gnu.org:/cvsroot/autoconf, module 
    'autoconf').
    install-sh may be set by configure as a substitute for the
    'install' program.  
    missing may be set by configure as a substitute for various GNU programs.
    mdate-sh is not currently used.

  GETCONFIG
    create API 'Rconfig.h' from the configure information in
    'config.h'.
  GETDISTNAME
    get the name of the distribution tarball.
  GETMAKEVAL
    get the value of a Make variable from a Makefile [this needs to
    be improved].  Used by configure.
  GETVERSION
    create API 'Rversion.h' from 'VERSION' and 'SVN-REVISION'.
  
  copy-if-change
    copy a file if changed; otherwise, do nothing.

  getsp.java
    Java source for share/java/getsp.class used for extracting
    system properties when detecting Java support in R CMD
    javareconf.  We don't require the existence of a Java
    compiler, so we need to supply the compiled version as well.

  help2man.pl
    generate simple manual pages from program output.  Taken from
    the GNU help2man package (https://ftp.gnu.org/gnu/help2man/).
    Used for a maintainer-mode build only: requires Perl.
    
  ldAIX4
    writes an export file, assembling the exported symbols by
    reading the output of nm.  This file is needed on AIX (4.2 and
    later) to compile shared libs.

  link-recommended
    create links with simplified names to the recommended packages.

  ltmain.sh
    provide generalized library-building support services.  Taken
    from Libtool 2.2.6a.

  move-if-change
    move a file if changed; otherwise, remove.

  rsync-recommended
    obtain sources for the recommended packages using rsync, and then
    create links with simplified names to these.

  updatefat
    updates a fat file by adding a new architecture (macOS only)
    it is essentially a smart wrapper for "lipo".  (No longer used.)

GETCONFIG, GETVERSION, copy-if-change and move-if-change are used on Windows,
and require cmp, cp, echo, expr, grep, mv and sed.
