how does this do (untested) :

   harp:~ > cat a.rb

   require 'yaml'
   class TclIndex
     def initialize arg
       @procs, @vars = {}, {}
       parse arg
     end
     def parse a
       read = lambda{|io| io.readlines.map!{|l| l.gsub %r/#.*$/, ''}}
       lines = a.respond_to?('readlines') ? read[a] : open(a){|f|read[f]}
       lines.each do |line|
         case line
           when %r/^ \s* proc \s+ (\w+)/iox
             @procs[$1] = -1
           when %r/^ \s* set \s+ (\w+)/iox
             @vars[$1] = 0
         end
         @procs.keys.each{|k| @procs[k] += 1 if line[%r/\b#{ k }\b/]}
         @vars.keys.each{|k| @vars[k] += 1 if line[%r/\b#{ k }\b|\$#{ k }\b/]}
       end
     end
     def report o
       o << {
         'procs' => @procs.to_a.sort_by{|ab| ab.last}.map{|ab| Hash[*ab]},
         'vars' => @vars.to_a.sort_by{|ab| ab.last}.map{|ab| Hash[*ab]},
       }.to_yaml
     end
   end


   abort "Usage: [inputfilepath = stdin] [outputfilename = stdout]" if
     ARGV.delete('help') or ARGV.delete('--help')

   i = ARGV.shift || STDIN
   o = ARGV.shift || STDOUT

   idx = TclIndex.new i
   idx.report o
