[R] Pseudo R^2 for logit - really naive question

[Paul M. Jacobson]

I am using GLM to calculate logit models based on cross-sectional data.  I
am now down to the hard work of making the results intelligible to very
average readers.  Is there any way to calculate a psuedo analoque to the R^2
in standard linear regression for use as a purely descriptive statistic of
goodness of fit? Most of the readers of my report will be vaguely familiar
and more comfortable with R^2 than with any other regression diagnostics.
