4# srctree.bbclass enables operation inside of an existing source tree for a
5# project, rather than using the fetch/unpack/patch idiom.
6#
7# By default, it expects that you're keeping the recipe(s) inside the
8# aforementioned source tree, but you could override S to point at an external
9# directory and place the recipes in a normal collection/overlay, if you so
10# chose.
11#
12# It also provides some convenience python functions for assembling your
13# do_clean, if you want to leverage things like 'git clean' to simplify the
14# operation.

39 This is necessary because of recipe variants (normal, native, cross,
40 sdk). If a bitbake run happens to want to build more than one of
41 these variants in a single run, it's possible for them to step on one
42 another's toes, due to the shared ${S}. Interleaved
