Better encapsulate the resolution names before include:

[Ducasse]

ast := Microdown parseFile: '/Users/ducasse/Workspace/FirstCircle/MyBooks/Bk-Writing/PharoBooks2/BuildingApplicationWithSpec2/index.md' asFileReference.

Microdown 
	resolveDocument: ast 
	withBase: '/Users/ducasse/Workspace/FirstCircle/MyBooks/Bk-Writing/PharoBooks2/BuildingApplicationWithSpec2/index.md'  asFileReference asMicResourceReference.

inclusionVisitor := MicFileIncluder new.
inclusionVisitor topFile: '/Users/ducasse/Workspace/FirstCircle/MyBooks/Bk-Writing/PharoBooks2/BuildingApplicationWithSpec2/index.md' asFileReference.
inclusionVisitor visit: ast.

vis := MicSBALaTeXWriter new.
vis visit: ast. 
vis contents
