The script uninstall_sifdec is used to remove a previously installed instance of SifDec from your system. If called with no argument, the user is asked to choose which distribution to remove, from a list of all the instances found on the system. Otherwise, the only argument is the name of the directory containing the distribution to be removed. We illustrate the second case. Referring again to Table 1.1, assume we wish to remove the Compaq-Alpha distribution. This is done by issuing the command
prompt% uninstall_sifdec $SIFDEC/SifDec.large.alp.t64.f90
at the command prompt. If this directory contains both the single and double precision instances, you will be prompted for which should be removed. There is no possibility, at the moment, to remove both instances at once. If single or double precision instance only is present, the whole directory will be deleted as will the corresponding entry in $SIFDEC/log/install.log. Note that un-installing should be done from the same machine from which the installation command was issued, as the corresponding directory might not be recognized on other machines. Issuing the command
prompt% uninstall_sifdec -help
will display a short help message. The script is itself self-documented and the user may consult it for more information.
