-// The host_snapshot module creates a snapshot of host tools to be used
-// in a minimal source tree.   In order to create the host_snapshot the
-// user must explicitly list the modules to be included.  The
-// host-fake-snapshot, defined in this file, is a utility to help determine
-// which host modules are being used in the minimal source tree.
-//
-// The host-fake-snapshot is designed to run in a full source tree and
-// will result in a snapshot that contains an empty file for each host
-// tool found in the tree.  The fake snapshot is only used to determine
-// the host modules that the minimal source tree depends on, hence the
-// snapshot uses an empty file for each module and saves on having to
-// actually build any tool to generate the snapshot.  The fake snapshot
-// is compatible with an actual host_snapshot and is installed into a
-// minimal source tree via the development/vendor_snapshot/update.py
-// script.
-//
-// After generating the fake snapshot and installing into the minimal
-// source tree, the dependent modules are determined via the
-// development/vendor_snapshot/update.py script (see script for more
-// information).  These modules are then used to define the actual
-// host_snapshot to be used.  This is a similar process to the other
-// snapshots (vendor, recovery,...)
-//
-// Example
-//
-// Full source tree:
-//   1/ Generate fake host snapshot
-//
-// Minimal source tree:
-//   2/ Install the fake host snapshot
-//   3/ List the host modules used from the snapshot
-//   4/ Remove fake host snapshot
-//
-// Full source tree:
-//   4/ Create host_snapshot with modules identified in step 3
-//
-// Minimal source tree:
-//   5/ Install host snapshot
-//   6/ Build
-//
-// The host-fake-snapshot is a singleton module, that will be built
-// if HOST_FAKE_SNAPSHOT_ENABLE=true.
