Introduce the below command-line tool:
textnotice outputs a NOTICE text file constructed from the license
texts of the transitive closure of dependencies.

Defer edge creation.
Don't create edges until the count is known to avoid repeated allocate+
copy operatios.
Limit resolutions.
Allow only a single resolution condition set per target, and overwrite
intermediate results. Reduces memory and obviates allocations.
Propagate fewer conditions.
Instead of propagating notice conditions to parents in graph during
initial resolve, leave them on leaf node, and attach to ancestors in
the final walk. Reduces copies.
Parallelize resolutions.
Use goroutines, mutexes, and waitgroups to resolve branches of the
graph in parallel. Makes better use of available cores.
Don't accumulate resolutions inside non-containers.
During the final resolution walk, only attach actions to ancestors from
the root down until the 1st non-aggregate. Prevents an explosion of
copies in the lower levels of the graph.
Drop origin for scale.
Tracking the origin of every potential origin for every restricted
condition does not scale. By dropping origin, propagating from top
to bottom can prune many redundant paths avoiding an exponential
explosion.
Conditions as bitmask.
Use bit masks for license conditions and condition sets. Reduces maps
and allocations.

package to read, consume, and analyze license metadata and dependency
graph.
Includes the below command-line tools:
listshare outputs csv of projects to share to meet restricted and
reciprocal license requirements with one project per line. The first
field is the path to the project, and subsequent fields identify the
license resolutions as colon-separated target:annotations tuples.
checkshare outputs error messages to stderr for any targets where
policy dictates both sharing and not sharing the source-code, and PASS
or FAIL to stdout. exit status indicates success 0 or conflict found 1
