[boost] [Core] gdb/VS Pretty-printers for Boost

There's been a number of independent efforts to produce pretty-printers (or "visualizers") for different popular Boost libraries. The one I like most due to its thoughtful execution is probably this one https://github.com/ruediger/Boost-Pretty-Printer. But maintaining a set of pretty-printers out of tree is a challenge for all the usual reasons. Having libraries optionally supply and maintain them is much more sustainable. Would it be possible to define a small set of standard ways (file locations, build steps) for a library to store and install pretty-printers for gdb and/or Visual Studio? Thanks, Jeff
