Subject: more clanups, sort, show brackets in default values again, simplify comments
X-Git-Tag: silc.client.0.9.5~20
X-Git-Url: http://git.silcnet.org/gitweb/?p=silc.git;a=commitdiff_plain;h=70ac3febac27077e8c460ca0bb04a2eb0c145734

more clanups, sort, show brackets in default values again, simplify comments
and add descriptive comments as shown below:
  --with-option=DIR   use option [search in DIR/lib and DIR/include]
