-New in 0.6e:
+New in 0.7:
* Total rewrite of libtool, along with a new model for library building.
* Completely rewritten documentation for the new paradigm.
* Sane handling of broken system linkers, such as the ones on AIX
* Support for stripping libraries during installation.
* Library version information is now passed on the command line, not
through a version file.
-* Quote metacharacters in arguments to compile mode.
\f
Version 0.6 was never released.
\f
+* Implement `ld -r' on all platforms.
+
* Don't forget to find link_static_flag for native cc's on HP-UX and OSF/1.
* Write installcheck for the demo directory.
* GCC docs imply that all rs6000 code is PIC. See if it is true of
any other processors (like maybe powerpc).
+
+* Maybe choosing between ln -s and cp -p should be done in ltconfig,
+not ltmain.sh?
