looking for "wget"-like utility with "find"-like search

[Robert P. J. Day]

  is there a combination search/download utility i can use to both
find a given file at a remote repository (using a recursive search),
and download that file once i find it?

  here's the problem.  say i want to download the tarball
gcc-3.4.3.tar.bz2.  now, i happen to know that i can use "wget" as
long as i remember that gcc release tarballs live at (in this case,
for gcc-3.4.3):

ftp://sources.redhat.com/pub/gcc/releases/gcc-3.4.3/gcc-3.4.3.tar.bz2

if i want gcc-3.4.2, same deal -- just change the numbers above.

  however, say i want a snapshot release, like gcc-4.0-20041204.  now
*that* would live under:

ftp://sources.redhat.com/pub/gcc/snapshots/4.0-20041205/gcc-4.0-20041205.tar.bz2

so i have to remember (and probably encode) the different directory
naming convention for snapshots as opposed to releases.

  and say i choose to switch to another repo.  here we go again -- i'd
have to figure out the directory naming conventions for *that* repo
for "wget" to work.

  what would be nice would be to say, go to
ftp://sources.redhat.com/pub/gcc, and recursively search for a file
with a given name.  if you find it, bring it back.  (even better would
be to allow wildcards, so i could say, go get
"gcc-3.4.3.{tar.bz2,tar.gz,tgz}".  whichever one you find first, grab
it and that will do nicely.

  is there a standard utility that can do this?  i've poked around
variations of ftp, wget and rsync and haven't seen anything that will
solve the problem.

  thoughts?
