+"""gypd output module
+
+This module produces gyp input as its output.  Output files are given the
+.gypd extension to avoid overwriting the .gyp files that they are generated
+from.  Internal references to .gyp files (such as those found in
+"dependencies" sections) are not adjusted to point to .gypd files instead;
+unlike other paths, which are relative to the .gyp or .gypd file, such paths
+are relative to the directory from which gyp was run to create the .gypd file.
+
+This generator module is intended to be a sample and a debugging aid, hence
+the "d" for "debug" in .gypd.  It is useful to inspect the results of the
+various merges, expansions, and conditional evaluations performed by gyp
+and to see a representation of what would be fed to a generator module.
+
+It's not advisable to rename .gypd files produced by this module to .gyp,
+because they will have all merges, expansions, and evaluations already
+performed and the relevant constructs not present in the output; paths to
+dependencies may be wrong; and various sections that do not belong in .gyp
+files such as such as "included_files" and "*_excluded" will be present.
+Output will also be stripped of comments.  This is not intended to be a
+general-purpose gyp pretty-printer; for that, you probably just want to
+run "pprint.pprint(eval(open('source.gyp').read()))", which will still strip
+comments but won't do all of the other things done to this module's output.
+
+The specific formatting of the output generated by this module is subject
+to change.
