 Use pdflatex to compile.
-To rebuild index you need to prepare your texindy installation:
 
-* find the files `tex/inputenc/*.xdy`;
-* convert, say, cp1251.xdy to utf with `iconv -f cp1251 -t utf8 cp1251.xdy | sudo tee utf8.xdy` or something like that.
-
-Now you have the correct utf8.xdy! Use `texindy -L russian --codepage utf8 algebra.idx` to rebuild index.
+Use `texindy -L russian -C koi8-r -o algebra-koi.ind algebra.idx && iconv -f koi8-r -t utf-8 algebra-koi.ind > algebra.ind && rm algebra-koi.ind` to rebuild index.
