Thank you Vincent, that is a useful script! What I settled on was the following racket script. It defines two helpers that I call at the repl to start and stop my frtime dev work: #lang racket (require setup/link) (define install-path "C:/Program Files/Racket/collects/frtime") (define dev-path "C:/path/to/development/frtime/collection") (define start-developing-frtime (lambda () (start-developing-collection dev-path install-path))) (define stop-developing-frtime (lambda () (stop-developing-collection dev-path install-path) (define start-developing-collection (lambda (dev-coll-path install-coll-path) (links install-coll-path #:remove? #t) (links dev-coll-path))) (define stop-developing-collection (lambda (dev-coll-path install-coll-path) (start-developing-collection install-coll-path dev-coll-path))) Thank you all, -Patrick <div class="gmail_quote">On 25 July 2012 16:41, Vincent St-Amour <<a href="mailto:stamourv@ccs.neu.edu" target="_blank">stamourv@ccs.neu.edu</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Patrick, I usually keep multiple single-directory (i.e. not unix-style) Racket installs around, including one for development.
