+Under the lyx temp directory, content.lyx and its embedded files are usually

+$temp/$embDirName/file.lyx
+$temp/$embDirName/figure1.png for ./figure1.png)
+$temp/$embDirName/sub/figure2.png for ./sub/figure2.png)

+This works fine for embedded files that are in the current or deeper directory
+of the document directory, but not for files such as ../figures/figure.png.
+A unique name $upDirName is chosen to represent .. in such filenames so that
+'up' directories can be stored 'down' the directory tree:
+
+$temp/$embDirName/$upDirName/figures/figure.png for ../figures/figure.png
+$temp/$embDirName/$upDirName/$upDirName/figure.png for ../../figure.png
+
+This name has to be fixed because it is used in lyx bundled .zip file.
+
+Using a similar trick, we use $absDirName for absolute path so that
+an absolute filename can be saved as
+
+$temp/$embDirName/$absDirName/a/absolute/path for /a/absolute/path
