"""Generate files required for the build.
This function is in charge of generating all the .h/.cpp files derived
from input .webidl files. Please note that there are build actions
required to produce .webidl files and these build actions are
explicitly not captured here: this function assumes all .webidl files
are present and up to date.
This routine is called as part of the build to ensure files that need
to exist are present and up to date. This routine may not be called if
the build dependencies (generated as a result of calling this the first
time) say everything is up to date.
Because reprocessing outputs for every .webidl on every invocation
is expensive, we only regenerate the minimal set of files on every
invocation. The rules for deciding what needs done are roughly as
follows:
1. If any .webidl changes, reparse all .webidl files and regenerate
the global derived files. Only regenerate output files (.h/.cpp)
impacted by the modified .webidl files.
2. If an non-.webidl dependency (Python files, config file) changes,
assume everything is out of date and regenerate the world. This
is because changes in those could globally impact every output
file.
3. If an output file is missing, ensure it is present by performing
necessary regeneration.

"""Generate files required for the build.
This function is in charge of generating all the .h/.cpp files derived
from input .webidl files. Please note that there are build actions
required to produce .webidl files and these build actions are
explicitly not captured here: this function assumes all .webidl files
are present and up to date.
This routine is called as part of the build to ensure files that need
to exist are present and up to date. This routine may not be called if
the build dependencies (generated as a result of calling this the first
time) say everything is up to date.
Because reprocessing outputs for every .webidl on every invocation
is expensive, we only regenerate the minimal set of files on every
invocation. The rules for deciding what needs done are roughly as
follows:
1. If any .webidl changes, reparse all .webidl files and regenerate
the global derived files. Only regenerate output files (.h/.cpp)
impacted by the modified .webidl files.
2. If an non-.webidl dependency (Python files, config file) changes,
assume everything is out of date and regenerate the world. This
is because changes in those could globally impact every output
file.
3. If an output file is missing, ensure it is present by performing
necessary regeneration.
