# RailsFS, as written by _why_the_lucky_stiff
#
# Full instructions:
# http://redhanded.hobix.com/inspect/railsfsAfterACoupleMinutesOfToolingWithFuseWhoa.html
#
=begin
Instructions cut and paste from _why's blog:
Save the railfs.rb script as script/filesys in your Rails app. (If you'd
rather not cut-and-paste the above, it's here.)
Now, run mkdir ~/railsmnt. Then, script/filesys ~/railsmnt. The rules are as
follows:
* ls ~/railsmnt will give you a list of tables.
* ls ~/railsmnt/table will list IDs from the table.
* cat ~/railsmnt/table/id will display a record in YAML.
* vim ~/railsmnt/table/id to edit the record in YAML!
