;;; Commentary:
;; Here's a quick explanation of what the functions in this file do.
;; Suppose that you've downloaded local copies of two URLs:
;;
;; http://foo.bar/plic.txt
;; and http://foo.bar/ploc/bletch.ps
;;
;; using "psne" (for an alternative, see `brep', below); if the
;; environment variable $S is set to the default, that is, S=~/snarf,
;; then the local copies will be at
;;
;; ~/snarf/http/foo.bar/plic.txt
;; and ~/snarf/http/foo.bar/ploc/bletch.ps ;
;;
;; then if you place the point over "http://foo.bar/plic.txt" and type
;; `M-x brfl' you will visit the local copy of "plic.txt" in a buffer,
;; with `find-fline'; if you place the point over
;; "http://foo.bar/ploc/bletch.ps" and type `M-x brgvl' you will open
;; the local copy of "bletch.ps" with gv, with `find-pspage'; and if
;; you place the point over any one of these urls and type `M-x brep'
;; then you'll get a temporary buffer like this:
;; ______________________________________________________________
;; |# (find-psne-links "http://foo.bar/ploc/bletch.ps") |
;; |# http://foo.bar/ploc/bletch.ps |
;; | |
;; |* (eepitch-shell) |
;; |mkdir -p $S/http/foo.bar/ploc/ |
;; |cd $S/http/foo.bar/ploc/ |
;; |wget http://foo.bar/ploc/bletch.ps |
;; |echo 'http://foo.bar/ploc/bletch.ps' >> ~/.psne.log |
;; | |
;; | |
;; |--:**- *Elisp hyperlinks* All L1 (Fundamental)----------|
;; |______________________________________________________________|
;;
;; that you can use to download a local copy even if you have not
;; installed the rcfile patches with eev-rctool to have a "psne"
;; command function available in the shell.
;;
;; See <http://angg.twu.net/eev-article.html#local-copies>.
;;
;; Notes:
;; A log of the local copies is stored at: (find-fline ".psne.log")
;; and these local copies can be "visited" with brfl, brgvl, brml,
;; brwl, etc.
