+# meshlab
+Meshlab project cloned in entirety but only using two files: "Parser" and "Scanner" in order to
+reformat .wrl/.x3dv files as .xml
+
+## Automatic repo clone
+Meshlab repo is automatically cloned.  Users who haven't opted-in to VRML support
+won't be burdened with the extra download volume.
+
+To update the git commit hash pulled down, modify `Meshlab_GIT_TAG` in file
+`code/CMakeLists.txt`; it is not expected that the sole files of interest "Parser" and "Scanner"
+will change frequently, if at all, going forward

+# meshlab patch
+
+## Notes
+Depending on user's OS, build environment etc it may be necessary to change line endings of
+`patches/meshlab.patch` file from `CRLF` to `LF` in order for patch operation to succeed
+
+## Overview
+"Parser" based on QtXml, need to change to use pugixml
+
+## pugixml notes
+Note that it isn't possible to add an unattached pugixml Node object, modify it, then
+add it to the tree later; the node needs to be attached somewhere in the tree on instantiation
+(even if it's a temporary at root level to be removed when finished) before populating, adding
+children etc.
