| **Note:** I decided to put the whole thing under version control. At the same time, I moved it from my lib folder to my project folder. So the current ÚFAL location is ''/home/zeman/projekty/interset/lib''. | |

| The drivers are Perl modules and must be somewhere under ''$PERLLIB'' (''@INC''). Their root folder is ''tagset'' (this is what separates the tag set drivers from other Perl libraries). Subfolders of ''tagset'' are two-letter codes of languages (ISO). Some tagsets may be designed for more than one language but most are language-specific. PM files in language folders are drivers. Drivers are called xxx.pm, where xxx is the code name of the tagset.

| There is also the driver testing script, ''bin/driver-test.pl''. The distribution may contain some sample conversion scripts as well; however, these depend much more on the file format than on the tagset drivers, and thus you'll probably need to write your own anyway. | There is also the driver testing script, ''bin/driver-test.pl''.

| | ===== How to use the Interset ===== |
| |
| | You can write your own tag conversion Perl script, and use the Interset driver library. You have to tell Perl where to find the drivers (the following commands work in ''csh''; you have to use different syntax under ''bash'' or in Windows command line): |
