+# lex
+
+> Lexical analyzer generator.
+> Given the specification for a lexical analyzer, generates C code implementing it.
+> More information: <https://manned.org/lex.1>.
+
+- Generate an analyzer from a Lex file, storing it to the file `lex.yy.c`:
+
+`lex {{analyzer.l}}`
+
+- Write analyzer to `stdout`:
+
+`lex -{{-stdout|t}} {{analyzer.l}}`
+
+- Specify the output file:
+
+`lex {{analyzer.l}} --outfile {{analyzer.c}}`
+
+- Generate a [B]atch scanner instead of an interactive scanner:
+
+`lex -B {{analyzer.l}}`
+
+- Compile a C file generated by Lex:
+
+`cc {{path/to/lex.yy.c}} --output {{executable}}`
