[llvm-commits] [llvm-top] r38518 - in /llvm-top/trunk: get library.sh

[Reid Spencer]

Author: reid
Date: Tue Jul 10 20:03:00 2007
New Revision: 38518

URL: http://llvm.org/viewvc/llvm-project?rev=38518&view=rev
Log:
First shot at Bourne shell based tools for managing checkout, configure, build.
The library.sh script contains enough to extract module dependencies in the
right order while the get script simply calls library.sh to checkout one or
more modules and their dependencies. To follow: configure, build, and maybe
other scripts.

    llvm-top/trunk/get   (with props)
