This directory contains SHILKA is oriented to fast recognition of keywords and standard identifiers in compilers. SHILKA is analogous to GNU package `gperf' but based on minimal pruned O-trie which can take into accout the frequency of keyword occurences in the program. Gperf can not make it. SHILKA is up to 20% faster than Gperf. SHILKA is also simpler than Gperf in the usage. To install SHILKA see file INSTALL in the current directory. Documentation of SHILKA is in files `shilka.1', `shilka.txt', `shilka.dvi', `shilka.ps', `shilka.info*', `shilka*.html', `shilka*.rtf'.
