X-Git-Tag: v3.6.0~2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0ecf26fc7d2f24570b4c04a668c437b8656a40a7;p=thirdparty%2Fiproute2.git

Change how pdf doc's are created

 Currently the pdf docs are done with
    sgml -> sgmltool -> tex -> latex -> dvi -> dvips -> ps -> ps2pdf -> pdf
 or
    tex -> latex -> dvi -> dvips -> ps -> ps2pdf -> pdf
 with this patch we do
    sgml -> sgmltool -> tex -> pdflatex -> pdf
 or
    tex -> pdflatex -> pdf
