Jack Nagel 8c29982153 Revert "Rename readline to gnu-readline"
This reverts commit adee5315265cc46aa6a3057071527abb16e1cd94.

Turns out one of the "other things" is a dealbreaker.

We only create kegs using a formula's canonical name. However, we do not
check that this is the case when mapping existing kegs back to formula
objects, and thus a keg with a name that happens to be an alias can fool
Homebrew into thinking the canonically-named keg exists.

So anything that enumerates kegs and then tries to do stuff with the
resulting formula objects will just break. This is obviously worse than
the debugger being broken, so reverting this for the time being.

1) This formula links the latest version of the Asymptote LaTeX and ConTeXt
packages into:
#{HOMEBREW_PREFIX}/share/texmf
In order for these packages to be visible to TeX compilers, the above
directory will need to be added to the TeX search path:
sudo tlmgr conf texmf TEXMFHOME "~/Library/texmf:#{HOMEBREW_PREFIX}/share/texmf"
2) If you want to have Asymptote compiled with support for fftw or gsl
(fast fourier transforms or the GNU Scientific Library) they must be
manually installed first:
brew install fftw
brew install gsl
They are not compiled by default because they take a long time to compile
and they are not required by most users. (And they're not included in the
TeX Live build of Asymptote.)
3) If you wish to use xasy, you must first install the Python Imaging
Library (PIL):
easy_install http://effbot.org/downloads/Imaging-1.1.7.tar.gz
