The problem with glob is that it doesn't by default show the so-called
"hidden" files (which on Unix-like system have a name beginning with a
dot). If you want absolutely all the files, you should use the
'entries' method of a Dir object that get you the same result as a 'ls
-a', but then you also get '.' (the current working directory) and
'..' (the parent directory) which you usually would want to get rid
of.

>> d = Dir.new(Dir.pwd)
=> #<Dir:/Users/jfleck/cours/sites/pcsi>
>> d.entries
=> [".", "..", ".DS_Store", "config.yaml", "MD5SUM", "MD5SUM_OLD",
"metainfo.yaml", "mise_a_jour_site_web_mpsi.rb", "output", "README",
"src", "truc"]

Cheers,
