.IX Header "DESCRIPTION"
The Alt::Base class provides common functionalities for an alternate module. For
more information about the Alt concept, please refer to Alt.
.PP
Alt::Base defines an \f(CW\*(C`import()\*(C'\fR routine which checks for options in \f(CW%ALT\fR.
These options are:
.IP "\(bu" 4
check => \s-1BOOL\s0 (default: 1)
.Sp
If set to true (the default), will perform several things. First, check that the
alternate module is indeed named \f(CW\*(C`Alt::<<Original::Module>::<phrase>\*(C'\fR.
Then, load \f(CW\*(C`Alternate::Module\*(C'\fR and check that the package variable \f(CW$ALT\fR is
defined with the value of \f(CW\*(C`phrase\*(C'\fR. This is to ensure that we are loading the
correct module, and sometimes we do want to make sure about this. The wrong
module can be loaded, for example if user reinstalls the original distribution
or another alternate distribution.
.Sp
Will die upon failure.
