Glynx - a download manager. 

Version history:

 1.026:
	- simple GET and PUT forms
	- reject link "c:\"
	- bigger max-link-len (500 bytes)
	- slave intervals on SLEEP if it is active; otherwise on TIMEOUT
	- ftp-dir sends content-location
	- finds ftp.pm in program's directory
	- better make-dir
	- escapes single-quotes reading config-file
	- corrected: didn't start if had --prefix
	- resume ftp transfers. Needs the custom ftp.pm module.
	- base-dir is always absolute
	- makerel: default is don't make backup
	- verify each subdirectory for transformations
	- sites with ports translate back correctly to site:port
	- make_shorter_name receives untransformed url also
	- separated pod file
	- saves Content-Type
	- can save any file attribute (delimiter is space)
	- reprocessing the cache is slower, due to relative links reconstruction
	- might create directories for linked sites, if it is necessary to create reference files

 1.025:
	- correction (again...) in slave mode variables save/restore
	- included simple web front-end in eg directory

 1.024:
	new options:
  	--name-len-max=   Limit filename size
  	--dir-depth-max=  Limit directory depth
	--cookies=FILE
	--auth=
	--makerel         Make relative links

	- makerel will make relative links to other sites; 
	will process last depth; 
	save modified page and make a backup of the original page.
	- better error handling on command line url "protocol error"
	- use env_proxy
	- my_link started
	- $RETRY_TIMEOUT_MULTIPLIER set to 2


 1.023:

 1.021:
	- uses URI::Heuristic on command-line URL
	- shows error response headers (if verbose)
	- look at the 3rd parameter on 206 (when available -- otherwise it gives 500),
			Content-Length: 637055		--> if "206" this is "chunk" size
			Content-Range: bytes 1449076-2086130/2086131 --> THIS is file size
	- prefix of: http://rd.yahoo.com/footer/?http://travel.yahoo.com/
  	  should be: http://rd.yahoo.com/footer/
	- included: "wav"
	- sleep had 1 extra second
	- sleep makes tests even when sleep==0
