 """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.
