A small unix and windows lib to search for executables in path folders.
Example: ```rs use searchpath::search_path; use std::ffi::OsString;
fn main() {
let path = std::env::varos("path");
let pathext = std::env::varos("pathext");
let files = searchpath("explo", path.asref().map(OsString::asosstr), pathext.asref().map(OsString::asos_str));
for file in files {
println!("{}", file);
}
}
Will print something like
bat
bashbug
bash
base32
basenc
basename
base64
```
