a set of nodes, each optionally containing +# information about the components it selects, depends on or conflicts +# with. +# +# The depresolver script returns two things: +# +# * A set of key-value pairs, indicating for each component whether +# it was enabled or not. +# * A second set of key-value pairs, associating to each component +# the set of enabled components it depended upon. +# +# The first set is used to determine which sources to compile in, +# using the dictionaries present in the relevant meson.build definitions +# in the subdirectories (eg. libavutil/meson.build) +# +# The second set is used to compute the external dependencies passed +# to the various build targets, when a component is compiled into library +# we check whether a @0@_flattened_deps.format(component) variable was +# set, and add it to the set of dependencies for that library. +# +# Various other python scripts have been implemented to reproduce other +# bits of logic in the configure script, eg.
