[izpack-devel] Variable names with hyphens used as folder names don't work

[Mike Patterson]

When I define a variable using a name with hyphens, and the name is used
for a directory, using the variable results in a directory with the same
name as the variable name being created, rather than a directory
accessed using the name the variable is set to. 
 
For example, I set the variable "Folder-name" to "test" and use a <file>
targetdir="$Folder-name". Instead of files being written into the folder
"test", they are written into a new folder named "$Folder-name"
(literally $Folder-name). If I use underscores in the variable name as
in "Folder_name", it works as expected.
