* Makefile.in (install): Do install.man if we have pod2man.
* Makefile.in: Make wget man page and install it if we have pod2man. Added some
missing '$(srcdir)/'s. Added missing dependencies on install targets
(allowing you to just do `make install' rather than forcing you to do `make &&
make install'). Also, Makefile rules should always use output file parameters
if available rather than redirecting stdout with '>', or you falsely satisfy
dependencies if the tool you're running is missing or fails -- fixed call of
texi2pod.pl that did this wrong.
* texi2pod.pl: Removed from CVS. Now automatically generated.
* texi2pod.pl.in: This new file is processed into texi2pod.pl, getting the
appropriate path to the Perl 5+ executable on this system and becoming
executable (CVS files, by contrast, don't arrive executable).
* TODO: Remove empty directories created due to --accept/--reject.
+ * configure.in: Look for perl and pod2man and make substitutions.
+
+ * Makefile.in (install): Do install.man if we have pod2man.

-* It would be nice to have a simple man page for wget that refers you to the
- .info files for more information. It could be as simple as the output of wget
- --help plus some boilerplate. This should stop wget re-packagers like RedHat
- who include the out-of-date 1.4.5 man page in order to have one. Perhaps we
- can automatically generate a man page from the .texi file like gcc does?
-
* Try to devise a scheme so that, when password is unknown, Wget asks
the user for one.
