+# Flex
+
+Flex (Fast Lexical Analyzer Generator) is a tool for generating programs that recognize patterns in text. It allows for the versatility to specify the rules for pattern-finding, eradicating the need to develop a specialized program.
+
+## Description
+
+Flex is a free software alternative to the classic lex tool. It generates C source code for scanners that can recognize regular expressions. The generated scanners are highly efficient and suitable for use in a wide variety of applications, from simple text processing to complex lexical analysis in compilers.
+
+## Features
+
+- Fast lexical analyzer generation
+- Compatible with original lex specifications
+- Generates efficient C code
+- Supports extended regular expressions
+- Cross-platform compatibility
+- Active development and maintenance
+
+## Installed Programs
+
+- **flex**: The main lexical analyzer generator
+- **flex++**: A symbolic link to flex for C++ code generation
+- **lex**: A symbolic link to flex for lex compatibility mode
+
+## Installed Libraries
+
+- **libfl.so**: The flex library containing support functions
+
+## Documentation
+
+Comprehensive documentation is installed in `/usr/share/doc/flex-2.6.4/` including:
+
+- Manual pages
+- Examples
+- Technical documentation
+- FAQ
+
+## Compatibility
+
+Flex maintains compatibility with the original lex tool while providing many enhancements and improvements. Programs that expect lex can use the provided lex symbolic link.
