+\r
+This configure option is nice too, but the problem you pointed out was\r
+serious, (so, thanks for noting it). I went ahead and fixed this.\r
+\r
+I also spent some time making sure I (think I) understand how library\r
+sonames and library versions work. I did several investigations with\r
+libtool that convinced me it adds problems without any tangible benefit,\r
+(at least for the target platforms I'm aware of people using with\r
+notmuch).\r
+\r
+I finished this by establishing a 3-part library interface version,\r
+(initially 1.0.0), along with careful documentation in the Makefile on\r
+how to increment it. And of course, I ended up touching up about a\r
+half-dozen issues in the Makefiles along the way.\r
+\r
+We'll still want to add functions/macros to the library to make the\r
+library version available to the user. And I do want to still add some\r
+symbol hiding and potentially some symbol versioning to the library. But\r
+I'm not making the patch series block on that.\r
+\r
+Finally, I'm a tiny bit annoyed that now after a fresh checkout of\r
+notmuch and "make" that one can't easily run ./notmuch without either\r
+installing the library (or fiddling with LD_LIBRARY_PATH). I've got some\r
+ideas on how to simplify that, but I'm not sure if any are good or worth\r
+it.\r
+\r
+Anyway, this patch series is now pushed with my changes on top. Thanks,\r
+Ben and Ingmar!\r
