a few doubts

[Xavier Noria]

I am just starting with PAR and got a few questions after reading the 
docs:

I want to distribute an application + data files both packaged and 
unpackaged. Can a script know whether it's being running from within a 
PAR file to decide how to read the data files?

If the application itself was a PAR file foo.par containing the 
executable foo.pl, and that application was bundled with data files in 
a second PAR bar.par, is there a way to execute foo.pl when bar.par is 
called?

This application will need to recreate some dir tree in disk (data 
files). Can packaged programs leverage PAR's temp dir somehow or would 
it be better to read_file() and manage a custom temp dir by hand?

Are paths to files in PAR archives using forward slashes portable?

PS: Just to give context, the application is an HTML presentation 
framework I plan to write with facilities for include listings, execute 
code and capture its output, in presentation time. The idea is to let 
authors distribute presentations as self-contained PAR files with the 
presentation engine bundled.
