specifically for macOS (OS X) won't make use of them, however applications ported from Linux or other Unices may have
dependencies that will only compile as dylibs. By default, there exists no mechanism to bundle them but some command-line utilities provided by Apple - however it turns out that for a single program it is often necessary to issue dozens of commands! This often leads each developer to create their own "home solution" which are often hacky, non-portable and/or suboptimal.
It automatically determines which dylibs are needed by your program, copies these libraries inside the app bundle, and fixes both them and the executable to be ready for distribution... all this with a single command! It will also work if your program uses plug-ins that have dependencies too.
Fixes given executable or plug-in file (a .dylib can work too. anything on which `otool -L` works is accepted by `-x`). dylibbundler will walk through the dependencies of the specified file to build a dependency list. It will also fix the said files' dependencies so that it expects to find the libraries relative to itself (e.g. in the app bundle) instead of at an absolute path (e.g. /usr/local/lib). To pass multiple files to fix, simply specify multiple `-x` flags.
> Dylibs in (path) will be ignored. By default, dylibbundler will ignore libraries installed in `/usr/lib` & `/System/Library` since they are assumed to be present by default on all macOS installations. *(It is usually recommend not to install additional stuff in `/usr/`, always use ` /usr/local/` or another prefix to avoid confusion between system libs and libs you added yourself)*
> Sets the name of the directory in wich distribution-ready dylibs will be placed, relative to the current working directory. (Default is `./Frameworks`) For an app bundle, it is often conveniant to set it to something like `./MyApp.app/Contents/Frameworks`.
> Sets the "inner" installation path of libraries, usually inside the bundle and relative to executable. (Default is `@executable_path/../Frameworks/`, which points to a directory named `Frameworks` inside the `Contents` directory of the bundle.)
*The difference between `-d` and `-p` is that `-d` is the location dylibbundler will put files in, while `-p` is the location where the libraries will be expected to be found when you launch the app (often using @executable_path, @loader_path, or @rpath).*
