Subject: libopkg: add option to strip ABI versions from listed names
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=d3a63b327383a2ac1a8f925a58a2f6a7808f5181;p=project%2Fopkg-lede.git

libopkg: add option to strip ABI versions from listed names

Listing packages without the ABI versions appended to their names is
needed in some situations. Add a new command line option '--strip-abi'
for that which affects the 'list' and 'list-installed' command.
