+#
+# Usage:
+#     ./bootstrap
+
+
+# This script should be installed, by starconf, in all `component
+# directories'.  A `component directory' is a directory which has a
+# component.xml.in file in it.  All component directories will have a
+# manifest file created and installed in .../manifests; non-component
+# directories will not have manifest files.  Everything that's
+# installed should be installed as part of some component
+# or other.
+#
+# The ./bootstrap scripts will stop recursing when they find a
+# component.xml.in file.  They'll warn if they find a component.xml.in
+# file in any AC_CONFIG_SUBDIRS directory, but ignore it, and exit
+# with an error if they do not find a component.xml.in file and there
+# are no AC_CONFIG_SUBDIRS directories in which to search further.
+# That is, the tree of directories which the top-level bootstrap
+# traverses should have component.xml.in files at or above all its
+# leaves.
+
+
+# The starconf below might update bootstrap, if a newer version is
+# available.  Unfortunately, this confuses sh, which appears _not_ to
+# keep open the script it's reading, but to reopen it afresh, or reseek
+# within the file, for each line (or something like that!?).
