This tool is intended to create 'shadow pages' (or 'ghost pages')
for ewiki internal/generated pages (the ["page"] plugins), which
usually weren't found by the PageSearch+ and PowerSearch.  This
admin plugin just innovocates those page plugins and puts their
html output into the database (which then can is found by the
search functions, but is never displayed, because the page plugins
still have precedence over that faked database content).

You cannot modify the README.plugins file, but anyhow any ideas or suggestion should as usually get filed on BugReports, UserSuggestions or even better the README.plugins.Discussion.
