Subject: Use -M parameter instead of --manpath when invoking man(1)
X-Git-Tag: v2.9.0-rc1~56
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=b07e7ef09b90a6bbb055f49bb2a6586dd45e73c9;p=lttng-tools.git

Use -M parameter instead of --manpath when invoking man(1)

Older versions of man (and the implementation used in FreeBSD) do
not support the long version of the --manpath/-M option. Use
'-M' in the interest of portability.

Fixes #1043
