• Completely restored the original text for "ORIGINAL MANIFESTO".
  I removed the reference to Module::Build (MB), as it is not well
  regarded by the Perl toolchain developers. Although not intended by
  me, it was suggested that it could seem a little sneaky. Instead I
  have restored the original text in that section, and added a caveat
  that MB seems to work well for Alien distrobutions, but is no longer
  universally preferred to ExtUtils::MakeMaker (EUMM).
  
• Added another caveat about Windows and Alien::MSYS
  
• Made some grammar tweaks/fixes that were apparent when I read the
  documentation out loud.
