ruby--ruby/lib/rdoc/ri/paths.rb
nobu 09cbac3f86 * lib/rdoc/ri/gemdirs.rb: split from lib/rdoc/ri/paths.rb to get
rid of loading rubygems and searching all gems always.

# Encapsulate all the strangeness to do with finding out where to find RDoc
# files
#
# We basically deal with three directories:
#
# 1. The 'system' documentation directory, which holds the documentation
# distributed with Ruby, and which is managed by the Ruby install process
# 2. The 'site' directory, which contains site-wide documentation added
# locally.
# 3. The 'user' documentation directory, stored under the user's own home
# directory.
#
# There's contention about all this, but for now:
#
# system:: $datadir/ri/<ver>/system/...
# site:: $datadir/ri/<ver>/site/...
# user:: ~/.rdoc
