The preferences file holds information about whether or not the user would
like to be notified about updates for individual packages. If the user is
on a Windows machine, the file will be in the
PEAR_CONFIG_SYSCONFIG directory and named
ppurc.ini. If the user is on any operating system, the
preferences file will be stored in the user's home directory as the file
.ppurc.
