Subject: If no nroff tool is found, or if no command line switch to nroff that converts
X-Git-Tag: cares-1_1_0~292
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=773e7e871e322526782efe44a1b64955ac3a77b1;p=curl

If no nroff tool is found, or if no command line switch to nroff that converts
a man page to text is found, we disable the built-in manual stuff to still
be able to build.
