For course 8, Publishing output from DITA sources, the lessons refer to b_ducks.ditamap and m_ducks.ditamap in the command for producing output.
In the downloaded sample files these are actually named _b_ducks.ditamap and _m_ducks.ditamap.
This generates errors when trying to produce the outputs.
My suggestion is to rename the files:
- /en-us/course08-publishing_output/samples/ducks/_b_ducks.ditamap -> b_ducks.ditamap
- /en-us/course08-publishing_output/samples/ducks/_m_ducks.ditamap > m_ducks.ditamap
And update the zip file for downloading.
While I am sure most people can work this out, it may be confusing for those learning DITA.
