[jsword-devel] Module Installation

[Troy A. Griffitts]

Sorry Joe,
The import lines are:

                entry = module->second.find("DataPath");
                if (entry != module->second.end()) {
                     SWBuf modDir = entry->second.c_str();
                     entry = module->second.find("ModDrv");
                     if (entry != module->second.end()) {
                          if (!strcmp(entry->second.c_str(), "RawLD") || 
!strcmp(entry->second.c_str(), "RawLD4") || 
!strcmp(entry->second.c_str(), "zLD") || !strcmp(entry->second.c_str(), 
"RawGenBook") || !strcmp(entry->second.c_str(), "zGenBook")) {
   // strip the last '/*'

Basically this says:

	Read the datapath and moddrv entries
	If (the moddrv is one in the list above) {
		then strip off from datapath the trailing '/whatever'

	use the datapath


Hope this helps.

Basically, datapath is either a directory or a directory/fileprefix. 
The moddrv type above use directory/fileprefix and need the /fileprefix 
removed to get the directory.

Chris is also right.  You should recurse into subdirectories.  We 
support images and these are usually grouped into an image subdirectory. 
  Our installmgr code does not yet do this but it is on our todo list :)

	-Troy.
