Hi, here's a very basic (and possibly stupid) question about the layout of gretl's C source. On the one hand, we have a directory lib/src/ with a lot of .c files (among others). On the other hand, we have gui/ or plugin/, also with many .c files. So my question: why the separate subdirectory "src" inside lib/, why are the .c files not directly inside lib/, like with the other directories? Inside lib/ there are only two other files: Makefile.in and README.libtool. Couldn't those files also live next to the source .c files? (Is README.libtool actually still current and/or needed?) Or vice-versa: why isn't there a gui/src/ or a plugin/src/ subdirectory? My guess is that it's purely historical, but maybe there's more to it. thanks sven
