INSTALL.txt missing ?

[strk]

Hi, I just git-pulled lily to take a look, but got side-tracked
by configure problems:

 $ ./configure
 ...
 ERROR: Please install required programs:  mpost
 See INSTALL.txt for more information on how to build LilyPond

but there's no INSTALL.txt ?

Since I'm at it... what I wanted to look INSTALL.txt for was
tips on where to find the required 'mpost'.

TIA
