/* The following class is the base class for all of the archive types.
* In order for it to work properly with the TDEProcess, you have to
* connect the ProcessExited signal appropriately before spawning
* the core operations. Then the signal that the process exited can
* be intercepted by the viewer (in ark, ArkWidget) and dealt with
* appropriately. See LhaArch or ZipArch for a good model. Don't use
* TarArch or CompressedFile as models - they're too complicated!
*
* Don't forget to set m_archiver_program and m_unarchiver_program
* and add a call to
* verifyUtilityIsAvailable(m_archiver_program, m_unarchiver_program);
* in the constructor of your class. It's OK to leave out the second argument.
*
* To add a new archive type:
* 1. Create a new header file and a source code module
* 2. Add an entry to the ArchType enum in arch.h.
* 3. Add appropriate types to buildFormatInfo() in archiveformatinfo.cpp
* and archFactory() in arch.cpp
