FSPath - CommonLISP style Namestring and Pathname Object

FSPath is an extension of unit utils pathname concept.

The extended pathname is referred to as a namestring.

The CommonLISP pathname object analog is the fs:pathname record object.

Namestring

Four styles of namestring are supported:

UNC

Universal Naming Convention, platform specific

FIL

Filename, platform specific

URI

Universal Resource Identifier

FSS

Filesystem Specific (Unimplemented)

Record fs:pathname

These namestring forms are mapped into fs:pathname components:

host

host descriptor - hostname, IP address, domain name

origin

drive, port, volume, device, logical name, environment variable

directory

list of fs:filename representing directory components

filename

fs:fIlename

The fs:pathname record is to be a logical pathname, portable across platforms.

Any missing component is represented by #f.

A SRFI-10 reader and printer are supplied.

Record fs:filename

These namestring forms are mapped into fs:filename components:

base

string or symbol

extensions

list-of string or symbol

version

positive integer, symbol oldest, or symbol newest

The fs:filename record is to be a logical filename, portable across platforms.

Any missing component is represented by #f.

A SRFI-10 reader and printer are supplied.

UNC

Windows:

\\<host>\<origin>\<directory>\<name>.<extension>[.<extension> ...]~<version>~

\\?\UNC\<host>\<origin>\<directory>\<name>.<extension>[.<extension> ...].~<version>~

Unix:

//<host>/<origin>/<directory>/<name>.<extension>[.<extension> ...].~<version>~

<host>:/<origin>/<directory>/<name>.<extension>[.<extension> ...].~<version>~

FIL

Windows:

<origin>:\<directory>\<name>.<extension>[.<extension> ...]~<version>~

\\?\<origin>:\<directory>\<name>.<extension>[.<extension> ...]~<version>~

Unix:

/<directory>/<base>.<extension>[.<extension> ...]~<version>~

FSS

This form is filesystem specific.

<specific>

Parameters
