Library and mix tasks to read and update Windows PE file resources. Based on https://docs.microsoft.com/en-us/windows/win32/debug/pe-format

*Only tested/needed with .exe files so far.*

## Example Usage

To check an existing PE file (.exe)

```bash
  mix pe.checksum <filename.exe>
```

To update the checksum:

```bash
  mix pe.update <filename.exe>
```

To list all resources in a file:

```bash
  mix pe.dump <filename.exe>
```

To set an icon resource (and update the checksum):

```bash
  mix pe.update --set-icon <icon.png> <filename.exe>
```



## Installation

To add LibPE to your build steps and make the tasks availabe add `libpe` to your list of dependencies in `mix.exs`:

```elixir
def deps do
  [
