is a variable defined in `
Its value is
A regexp that matches the end of the output from all cvs update programs.
That is, output from any programs that are run by CVS (by the flag -u
in the `modules' file - see cvs(5)) when `cvs update' is performed should
terminate with a line that this regexp matches. It is enough that
some part of the line is matched.
The default (a single $) fits programs without output.
You can customize this variable.
