 322 The summary includes project name, version, build hostname, host type (cross

 324 output is indexed in many ways to simplify browsing.")

 611 standards-compliant configure scripts and Makefiles for Python-based packages.
 612 It is designed to work alongside existing Python setup scripts, making it easy
 613 to integrate into existing projects.  Powerful and flexible Autoconf macros
 614 are available, allowing you to easily make adjustments to the installation
 615 procedure based on the capabilities of the target computer.")
