# SOFTWARE-EVOLUTION-LIBRARY

The SOFTWARE-EVOLUTION-LIBRARY enables the programmatic modification
and evaluation of software.

A common interface abstracts over multiple types of software objects
including source code abstract syntax trees (primarily using
[tree-sitter](https://tree-sitter.github.io/tree-sitter/)), compiled
assembler code, and binary software objects.  Software transformation,
analysis, and evaluation techniques are implemented on top of this
interface supporting automation of common software engineering tasks.

See the manual, available at [https://grammatech.github.io/sel](https://grammatech.github.io/sel/#Top).

SEL has been used to support many projects including:

programmatic modification and evaluation of extant software

A common interface abstracts over multiple
types of software objects including abstract syntax trees parsed from
source code, LLVM IR, compiled assembler, and linked ELF binaries.
Mutation and evaluation methods are implemented on top of this
interface supporting Search Based Software Engineering (SBSE)
techniques.
