the main manpage directory contains the manpage for the smbsh command htmldocs/manpages/smbsh.1.html
But the command itself is in the example directory examples/libsmbclient/smbwrapper/.
IMHO the command and the manpage belong together so both should be in the example directory or the command should be build and installed and the manpage stays where it is now.
in 3.0.28a the html documentation of the example code smbsh.c is still in the main documentation.
IMHO this should be removed from the main/installed documentation.
Fixed in all branches now.
Tahnk you very much for reporting!
Closing out bug report.
