 .SH DESCRIPTION
 .I sdcv 
-is simple, cross-platform text-base utility 
-for work with dictionaries in StarDict's format.
-The word from "list of words" may be string 
-with leading '/' for using  Fuzzy search algorithm, 
-with leading '|' for using full-text search,
-string may contain '?' and '*' for using regexp search.

+Each word from "list of words" may be a string

+and the string may contain '?' and '*' for regexp search.
+It works in interactive and non-interactive mode.
 To exit from interactive mode press Ctrl+D. 
 In interactive mode, 
 if sdcv was compiled with readline library support,
-you can use UP and DOWN keys to work through history.
