The code is based on two existing programs {\protect \protect \protect \edef T1{T1}\let \enc@update \relax \protect \edef cmr{cmr}\protect \edef m{m}\protect \edef n{n}\protect \xdef \T1/cmr/m/n/10 {\T1/cmr/m/n/10 }\T1/cmr/m/n/10 \size@update \enc@update \ignorespaces \relax \protect \relax \protect \edef cmr{cmtt}\protect \xdef \T1/cmr/m/n/10 {\T1/cmr/m/n/10 }\T1/cmr/m/n/10 \size@update \enc@update HDECAY} and {\protect \protect \protect \edef T1{T1}\let \enc@update \relax \protect \edef cmr{cmr}\protect \edef m{m}\protect \edef n{n}\protect \xdef \T1/cmr/m/n/10 {\T1/cmr/m/n/10 }\T1/cmr/m/n/10 \size@update \enc@update \ignorespaces \relax \protect \relax \protect \edef cmr{cmtt}\protect \xdef \T1/cmr/m/n/10 {\T1/cmr/m/n/10 }\T1/cmr/m/n/10 \size@update \enc@update SDECAY} for the calculation of the decay widths and branching ratios of, respectively, the MSSM Higgs bosons and the SUSY particles, and calls a program for the calculation of the SUSY particle spectrum such as {\protect \protect \protect \edef T1{T1}\let \enc@update \relax \protect \edef cmr{cmr}\protect \edef m{m}\protect \edef n{n}\protect \xdef \T1/cmr/m/n/10 {\T1/cmr/m/n/10 }\T1/cmr/m/n/10 \size@update \enc@update \ignorespaces \relax \protect \relax \protect \edef cmr{cmtt}\protect \xdef \T1/cmr/m/n/10 {\T1/cmr/m/n/10 }\T1/cmr/m/n/10 \size@update \enc@update SuSpect}. Including all important higher order effects, the package allows the consistent calculation of the MSSM particle spectrum and decays with the presently highest level of precision.
