libfl2 binary package in Ubuntu Mantic ppc64el

 Flex is a tool for generating scanners: programs which recognized lexical
 patterns in text. It reads the given input files for a description of a
 scanner to generate. The description is in the form of pairs of regular
 expressions and C code, called rules. Flex generates as output a C source
 file, lex.yy.c, which defines a routine yylex(). This file is compiled
 and linked with the -lfl library to produce an executable. When the
 executable is run, it analyzes its input for occurrences of the regular
 expressions. Whenever it finds one, it executes the corresponding C code.
 .
 This package contains the shared library for flex.
