Re: [racket-dev] lib changes between versions
Ah, these look like good approaches. First, I think I'll have to shore up my usage of raco setup now to be sure I'm generating zos correctly for the two different versions.

Re: [racket-dev] lib changes between versions
If your library's name is also `json` you could put in a place that is included in PLTCOLLECTS when you run v5.2.1, but use a PLTCOLLECTS that doesn't include it when your run v6.1 (in much the same way that you use different PLTCOMPILEDROOTS settings for the different versions). If your library has a different name, you could similarly point PLTCOLLECTS at it for v.5.2.1, and use a different implementation --- accessed either via PLTCOLLECTS or by installing as a package --- that wraps the main-distribution one for v6.1.

[racket-dev] lib changes between versions
I'm maintaining the same racket code between Racket version 5.2.1 and 6.1. One thing that changed between those version was the json to string (and vice versa) lib functions.

Re: [racket-dev] lib changes between versions
Actually this issue is still perplexing me. In 5.2.1 I have my own json lib which provides jsexpr-string. In 6.1 it's part of the distribution's collects directory. Is there a command line for racket that'll cause it to find mine under 5.2.1 and the standard lib in 6.1 (skipping mine)?
