The current git version of cryptsetup has support for opening of truecrypt volume.
The next version of cryptsetup with therefor have the ability to open truecrypt volumes,not creating them,just open them.
The current git version of zuluCrypt has the ability to open truecrypt volumes if the installed cryptsetup version is capable of opening them.
It will therefore be possible in the future to open cryptsetup luks volumes,cryptsetup plain volumes as well as truecrypt volumes using zuluCrypt and zuluMount simply by selecting a volume and zuluCrypt/zuluMount will do,as they say,"the right thing" :-)
The current git version of zuluMount can also mount file systems residing in files so its now possible to mount file systems residing in both partitions and files.
If you have an iso image file and you want it mounted,you can use zuluMount to do that.
The git version is stable and can be used as a stable branch.
