FreeBSD 15 - source of makefiles for base packages?

[Erichans]

For a packaged base FreeBSD 15, where can I find the source files, especially the Makefile's, for base packages?

 

[T-Daemon]

Look under src/release/packages, you will find there all pkgbase main creation files, under packages/sets meta packages template files, under packages/utc individual packages template files.
