%description
Evaluation for density and distribution function of convolution of gamma
distributions in R. Two related exact methods and one approximate method
are implemented with efficient algorithm and C++ code. A quick guide for
choosing correct method and usage of this package is given in package
vignette. For the detail of methods used in this package, we refer the
user to Mathai(1982)<doi:10.1007/BF02481056>,
