bin/install_scons.py

   1 #!/usr/bin/env python
   2 #
   3 # A script for unpacking and installing different historic versions of
   4 # SCons in a consistent manner for side-by-side development testing.
   5 #
   6 # This abstracts the changes we've made to the SCons setup.py scripts in
   7 # different versions so that, no matter what version is specified, it ends
   8 # up installing the necessary script(s) and library into version-specific
   9 # names that won't interfere with other things.
  10 #
  11 # By default, we expect to extract the .tar.gz files from a Downloads
  12 # subdirectory in the current directory.
  13 #
  14 # Note that this script cleans up after itself, removing the extracted
  15 # directory in which we do the build.
  16 #
  17 # This was written for a Linux system (specifically Ubuntu) but should
  18 # be reasonably generic to any POSIX-style system with a /usr/local
  19 # hierarchy.
