rubibtex is used to run bibtex(1) on auxiliary files with Russian characters in item names (citation keys). It is part of the T2 package.
rubibtex copies the auxiliary file to /tmp, uses sed(1) to convert Cyrillic character commands to their 8-bit ASCII equivalents; runs bibtex(1) on the modified file; and finally moves the original auxiliary file back (overwriting the modified file).
The T2 package is Copyright 1997-1999 Werner Lemberg, Vladimir Volovich and any individual authors listed elsewhere in package files.
