The following command line options are accepted:
xindy [-h] [-t] [-v] [-l logfile] [-o outfile] [-L n] [-f filterprog] indexstyle raw-index
The argument indexstyle names a file, containing the index style description. The argument raw-index names a file, containing the raw index. Both arguments are mandatory.
Gives a short summary of all command line options.
Writes helpful information into the specified logfile. For example, the keyword mappings are written into this file, so one can check if the intended mappings were actually performed this way.
Explicitly defines the name of the output file. If not given, the name of the raw-index is used with its extension changed to .ind (or added, if it had no extension at all).
Enters tracing mode of the symbolic markup tags. The format of the emitted tags can be defined with the command markup-trace.
Set the xindy logging-level to n.
Run filterprog on raw-index before reading. The program must act as a filter reading from stdin and writing to stdout. The most obvious use of this option in conjunction with TeX is to run -f tex2xindy on the index file prior to reading the entries into xindy.
Shows the version number of xindy.
Errors and warnings are reported to stdout and additionally to the logfile if -l was specified.
The system uses the concept of a search path for finding the index style files and modules. The searchpath can be set with the environment variable XINDY_SEARCHPATH which must contain a list of colon-separated directories. If it ends with a colon, the built-in searchpath is added to the entire searchpath. See the command searchpath for further details.
