@pawosm-arm, thanks for looking into it. I got rid of the `.rst` files. When I added the explicit source suffix, it seemed like the man-page build needed the parser for the .md files. With the `myst_parser` library not being imported, I was hitting parsing errors of the .md files, so I explicitly changed the requirement. With that and adding placeholder missing `.md` files, I can generate a man doc at `${BUILD_DIR}/tools/flang/docs/man/flang.1`
