# Usage:
#
# rails_routes <or list, space separated> [options]
#
# include string is a valid shell glob: http://mywiki.wooledge.org/glob
#
# options are among
#
# * a valid shell glob pattern
# * -a <and glob>
# * -o <or glob>
# * -e <exclude (not) glob>
#
# Processing occurs as ((or list) AND (and list)) NOT (exclude list)
#
# Examples:
#
# rails_routes admin
# /admin/reports/agent/:id(.:format) {:controller=>"reports", :action=>"agent"}
#
# rails_routes "P@(OS|U)T"
# POST /current(.:format) {:action=>"create", :controller=>"current"}
# PUT /current/:id(.:format) {:action=>"update", :controller=>"current"}
#
# or, equivalently, rails_routes POST -o PUT
#
# List all routes containing admin but not test
# rails_routes admin -e test
