-Spawn is a small library exposing only one functionality: spawning sub-process.
-
-It has three main goals:
-
-1. provide missing features of Unix.create_process such as providing a
-working directory
-
-2. provide better errors when a system call fails in the
-sub-process. For instance if a command is not found, you get a proper
-[Unix.Unix_error] exception
-
-3. improve performances by using vfork when available. It is often
-claimed that nowadays fork is as fast as vfork, however in practice
-fork takes time proportional to the process memory while vfork is
-constant time. In application using a lot of memory, vfork can be
-thousands of times faster than fork.

+/**
+
+`Path` is a library for creating and operating on file paths consistently on
+all platforms.
+
+`Path` works exactly the same on Windows, Linux, and OSX, instead of adjusting
+behavior based on your current OS
+
+The `Path` API uses the following conventions:
+
+- Accepts/returns only `t(absolute))` for values that must be absolute paths.
+- Accepts/returns only `t(relative))` for values that must be absolute paths.
+- Accepts `t('any)` for values that may be either absolute or relative paths.
+- Returns `firstClass = Absolute(t(absolute)) | Relative(t(relative)` for
+  return values that could be either. Consumers must pattern match on it.
+- Wraps return values in `Some(..)` / `None` when it is possible that no
+  value may be computed even when the caller supplies valid data.
+- Wraps return values in `Ok(..)` / `Error(exn)` when it is possible that no
+  value may be computed due to an error occuring in either user input or system
+  failure.
+- For every `functionName` that wraps return values in `Ok`/`Error`, an
+  alternative form `functionNameExn` is also supplied which does not wrap
+  the return value, and instead raises an exception.
+
+TODO: Consider the following universal convention instead:
+
+    type specificUsageError = UserNameInvalid | LoggedOut;
+    type blame('usage) = | Caller('usage) | Implementation(exn);
+    // Returns Error only for system blame:
+    result(x, exn)
+    // Returns Error for caller/system blame
+    result(x, blame(usage))
+    // Returns Error only for caller blame
+    result(x, usage)
+    // Returns Error for caller/system blame, but no value expected.
+    result(option(x), blame(usage))
+    // Returns Error for system blame, but no value expected.
+    result(option(x), exn)

+
+Exceptions:
+If it is impossible to create a relative path from `soure` to `dest` an
+exception is raised.
+If `source`/`dest` are absolute paths, the drive must match or an exception is
+thrown. If `source`/`dest` are relative paths, they both must be relative to
+`"~"` vs. `"."`. If both are relative, but the source has more `..` than the
+dest, then it is also impossible to create a relative path and an exception is
+raised.
