allowing a hierarchy of caches, by using only one directory for each cache, and by putting only one command in the PATH. - scripts/dsv: new and improved data sheet viewer (successor of gta02-core's dsv) - Makefile: added "dsv" target to update the bookshelf - ds/INFO, components/INFO, modules/INFO: ds/INFO moved to BOOKSHELF - components/INFO, modules/INFO: renamed "D" tag to "N", for consistency with BOOKSHELF - BOOKSHELF: changed "stdpass" URL to the actual PDF

# dsv - Improved data sheet viewer
|
|
#
|
|
|
|
#
|
|
# Theory of operation:
|
|
#
|
|
# We download data sheets from the Internet into local caches and provide a
|
|
# quick access mechanism for viewing the data sheets. A cache is a directory
|
|
# called .dsv/. Caches can be hierarchical. "dsv setup" generates a cache in
|
|
# the local directory. "dsv <component>" and "dsv ls" search the hierarchy,
|
|
# starting with the current directory.
|
|
#
|
|
# Caches contain two types of files: dsv-<ref> is the name or alias with
|
|
# which a data sheet is referenced. <ref>-<filename> is the actual data
|
|
# sheet, with <filename> being the name of the file we downloaded.
|
|
