All the packages that form the perl interface to Aegisub are automatically
loaded, however none of their symbols are exported initially. If you want to
import them you can use the usual 'use' mechanism; if you call it without a
list of imports it will import more or less everything (exceptions to this are
explicitely signaled in the docs) in your script's package.

package. Wether they are exported or not is indicated in the following
reference by <--EXPORTED--> (exported by default within a plain 'use'
statement) and <--EXPORTABLE--> (can be imported specifying them explicitely in
the 'use' statement) tags. Finally, <--NOT EXPORTABLE--> indicates symbols that
can't be exported through 'use'.

package Aegisub::Progress
------------------------------------
This package provides an interface to the progress window automatically showed
during the execution of a feature. Its functions are somewhat different to
those available in lua because of clarity, however aliases are given. You can
see this in the following list: wherever a function has two names the first is
the 'official' one and is automatically exported with 'use Aegisub::Progress',
while if you want to use the second one you'll have to explicitely import them.
