`preload-rs` is a daemon process that prefetches binary files and shared libraries

from the hard disc to the main memory of the computer system to achieve faster

application startup time. `preload-rs` is adaptive: it monitors the application that

the user runs, and by analyzing this data, predicts what applications he might

run in the near future, and fetches those binaries and their dependencies into

memory.

It builds a Markov-based probabilistic model capturing the correlation between

every two applications on the system. The model is then used to infer the

probability that each application may be started in the near future. These

probabilities are used to choose files to prefetch into the main memory. Special

care is taken to not degrade system performance and only prefetch when enough

resources are available.

## Design

`preload-rs` has been divided into the following crates, with each crate serving a specific purpose. They are:

- `cli`: Responsible for launching `preload-rs` process. It is a binary crate.

- `config`: Manages configuration for `preload-rs`. It is a library.

- `kernel`: Manages the core functionality of `preload-rs`. It is a library.

All crates reside under `crates/` directory.
