Source reorganization. In short:
* Added directories and moved related files into them: - src for the MPFR source files (to build the library). - doc for documentation files (except INSTALL, README...). - tools for various tools (scripts) and mbench. - tune for tuneup-related source files. - other for other source files (not distributed in tarballs). Existing directories: - tests for the source files of the test suite (make check). - examples for examples. - m4 for m4 files. * Renamed configure.in to configure.ac. * Added/updated Makefile.am files where needed. * Updated acinclude.m4 and configure.ac (AC_CONFIG_FILES line). * Updated the documentation (INSTALL, README, doc/README.dev and doc/mpfr.texi). * Updated NEWS and TODO. * Updated the scripts now in tools. The following script was used: #!/usr/bin/env zsh svn mkdir doc other src tools tune svn mv ${${(M)$(sed -n '/libmpfr_la_SOURCES/,/[^\]$/p' \ Makefile.am):#*.[ch]}:#get_patches.c} mparam_h.in \ round_raw_generic.c jyn_asympt.c src svn mv mbench check_inits_clears coverage get_patches.sh mpfrlint \ nightly-test update-patchv update-version tools svn mv bidimensional_sample.c speed.c tuneup.c tune svn mv *.{c,h} other svn mv FAQ.html README.dev algorithm* faq.xsl fdl.texi mpfr.texi \ update-faq doc svn mv configure.in configure.ac svn cp Makefile.am src/Makefile.am svn rm replace_all [Modifying some files, see above] svn add doc/Makefile.am svn add tune/Makefile.am git-svn-id: svn://scm.gforge.inria.fr/svn/mpfr/trunk@7087 280ebfd0-de03-0410-8827-d642c229c3f4
