The Needs::nocont message is generated when Needs["context"] finds that
"context" is not present in the value of $Packages. Since "context" is
prepended to $Packages as one of the first steps in evaluation of
BeginPackage["context"], the appearance of this message usually means
that BeginPackage["context"] hasn't been evaluated. The first thing
that I would do to solve this problem would be to take a close look at
the .m file with an ordinary text editor.
A diagonal line on the cell bracket is used to indicate that the cell is
a StandardForm cell.
