"""
Verify that rebuilds do not occur when SConsignFile(None) is used to
put a .sconsign file in each directory and we subdvide the dependency
tree with subsidiary *SConstruct* files in various subdirectories.

This depends on using content signatures for evaluation of intermediate
Nodes.  We used to configure this explicitly using
TargetSignatures('content'), but we now rely on the default behavior
being the equivalent of Decider('content').

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
