我想讓 SVN 告訴我它使用的 CA。svn help似乎沒有討論它（但我可能錯過了它，因為它在下面的子命令列表中並不明顯）。
我如何指示 subversion 列印其 CA 清單？
$ svn help
usage: svn <subcommand> [options] [args]
Subversion command-line client, version 1.7.10.
Type 'svn help <subcommand>' for help on a specific subcommand.
Type 'svn --version' to see the program version and RA modules
or 'svn --version --quiet' to see just the version number.
Most subcommands take file and/or directory arguments, recursing
on the directories. If no arguments are supplied to such a
command, it recurses on the current directory (inclusive) by default.
Available subcommands:
add
blame (praise, annotate, ann)
cat
changelist (cl)
checkout (co)
cleanup
commit (ci)
copy (cp)
delete (del, remove, rm)
diff (di)
export
help (?, h)
import
info
list (ls)
lock
log
merge
mergeinfo
mkdir
move (mv, rename, ren)
patch
propdel (pdel, pd)
propedit (pedit, pe)
propget (pget, pg)
proplist (plist, pl)
propset (pset, ps)
relocate
resolve
resolved
revert
status (stat, st)
switch (sw)
unlock
update (up)

Subversion is a tool for version control.
