Subject qpid-autotools-install script; ready to install
Date Mon, 18 Dec 2006 16:13:14 GMT
Here's the latest version of my script.
I think it's ready to commit.
It probably belongs in cpp/qpid-autotools-install.
Once there, you can do this:

  cd cpp
  chmod a+x qpid-autotools-install
  svn add qpid-autotools-install

Usage: $0 [OPTION]...
Download, build, and install some tools.

Options:
 --prefix=PREFIX    install tools under specified directory
 --skip-check       do not run "make check" (this can save 50+ min)
 --help             display this help and exit

For example, to install programs into $HOME/qpid-tools/bin, run this command:

  $prog_name --prefix=$HOME/qpid-tools

If you've already verified that your system/environment can build working
versions of these tools, you can make this script complete in just a
minute or two (rather than about an hour if you let all "make check"
tests run) by invoking it like this:

  $prog_name --prefix=$HOME/qpid-tools --skip-check
