(** Return [true] if the file name is relative to the current
directory, [false] if it is absolute (i.e. in Unix, starts
with [/]). *)
val is_relative : string -> bool
(** Return [true] if the file name is relative and does not start
with an explicit reference to the current directory ([./] or
[../] in Unix), [false] if it starts with an explicit reference
to the root directory or the current directory. *)

ends with the suffix [suff]. *)

the filename [name]. The behavior is undefined if [name] does not
end with the suffix [suff]. *)

(** Split a file name into directory name / base file name.
{!Filename.concat} [(]{!Filename.dirname}[ name) (]{!Filename.basename}[ name)]
returns a file name which is equivalent to [name]. Moreover, after setting the
current directory to {!Filename.dirname}[ name] (with {!Sys.chdir}),
references to {!Filename.basename}[ name] (which is a relative file name)
designate the same file as [name] before the call to {!Sys.chdir}. *)

(** [temp_file prefix suffix] returns the name of a
fresh temporary file in the temporary directory.
The base name of the temporary file is formed by concatenating
[prefix], then a suitably chosen integer number, then [suffix].
The temporary file is created empty, and is guaranteed to be
different from any other file that existed when [temp_file]
was called.
Under Unix, the temporary directory is [/tmp] by default; if set,
the value of the environment variable [TMPDIR] is used instead.
Under Windows, the name of the temporary directory is the
value of the environment variable [TEMP],
or [C:\temp] by default.
Under MacOS, the name of the temporary directory is given
by the environment variable [TempFolder]; if not set,
temporary files are created in the current directory. *)

(** Return a quoted version of a file name, suitable for use as
one argument in a shell command line, escaping any shell
meta-characters. *)
