 -- TODO/NOTES:
--- implement image removal
+-- M.checkValidImage(verEnt) -> doet exists+fileSize/MD5 check
--- make sure downloaded files are overwritten, and never named with '.n' suffix
+-- after download: (can use checkValidImage for this)
--- max 1 image tegelijk gedownload (zelfs dat is al link qua geheugengebruik? -> printen blokkeren vanaf download image?)
+-- - remove file on fail
+-- - check size or md5 and remove file on mismatch [osx: md5 -q <file>]
+-- add to status: validImage: none|<version> (can use checkValidImage for this)
+-- any more TODO's across this file?
+-- max 1 image tegelijk (moet api doen), en rekening houden met printbuffer (printen blokkeren?)
+-- API calls to add: update/status, update/download, update/install, update/clear
 
--- interpret wget return values more intelligently? or add function to run integrity check on index vs actually present files?
+-- MAYBE/LATER:
--- after downloading anything, check whether it really exists?
+-- wget: add provision (in verbose mode?) to use -v instead of -q and disable output redirection
--- document index file format (Version first, then in any order: Files: sysup; factory, ChangelogStart:, ..., ChangelogEnd:)
+-- wget: configurable timeout?
--- can we also get rid of the .lua extension? (looks nicer on command-line)
+-- max cache lifetime for index file?
+-- document index file format (Version first, then in any order: Files: sysup; factory, FileSize: sysup; factory, MD5: sysup; factory, ChangelogStart:, ..., ChangelogEnd:)
 -- remove /etc/wifibox-version on macbook...
--- perhaps create a function for each action and directly assign them in the arguments parser
+-- copy improved fileSize back to utils (add unit tests!)
+-- create new utils usable by updater as well as api? (remove dependencies on uci and logger etc)
