R-beta: stable distribution and stable glm package

I have just uploaded the package "stable-0.1.tgz" to the contrib section
of CRAN.

It enables to compute the density ('dstable'), the distribution
('pstable'), the quantile ('qstable') and the hazard ('hstable')
functions of a stable variate.

'stable.mode' computes the mode of a stable distribution.

The procedure 'stableglm' also enables to fit generalized linear models
for the parameters of a stable distribution interactively. 

This package was used to produce the results published in the  paper 
Lambert, P. and Lindsey, J.K. (1998) 'Generalized regression models
for heavy-tailed processes based on non-symmetric stable
distributions: a likelihood approach. (To appear in Applied Statistics)'

Note that 'rstable' is not a miracle of computation.
Implementing the Chambers, Mallows and Stuck (JASA 71: 340-44)
algorithm would certainly be preferable for 'rstable'.

Bug reports and suggestions are of course welcome.
