# This test is used to verify that the Buildability of a set of nodes
# is unaffected by various querying operations on those nodes:
#
# 1) Calling exists() on a Node (e.g. from find_file) in a VariantDir
#    will cause that node to be duplicated into the builddir.
#    However, this should *not* occur during a dryrun (-n).  When not
#    performed during a dryrun, this should not affect buildability.
# 2) Calling is_derived() should not affect buildability.

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.
