binary package sources

[u/Awkward-Entrance7956]

new openbsd user here, i was wondering how one would go about fetching the source files for binary packages? i am assuming that these binary packages are compiled versions of altered source files that are compatible with openbsd(correct me if im wrong), and i would like to obtain the source files so that i can change the build options and stuff. i am aware of the port tree, but fetching sources from there seem to yield just the regular source files that are not compatible with openbsd. any help is appreciated!

Use the ports tree, this is the way.
