"file name.tex"
(for example), which
helps somewhat, but while this allows us to say
the analogous usage\input "foo bar.tex"
using “ordinary” LaTeX causes confusion in xdvi and dvips, even though it works at compilation time. Sadly, even within such quotes, multiple dots give\includegraphics{"gappy graphics.eps"}
\
includegraphics
difficulties. Note that
works in a similar version of PDFTeX. If you’re using the graphics package, the grffile package will help. The package offers several options, the simplest of which are\includegraphics{"gappy graphics.pdf"}
multidot
(allowing more than one dot in a
file name) and space
(allowing space in a file name). The
space
option requires that you’re running on a
sufficiently recent version of PDFTeX, in PDF mode — and
even then it won’t work for MetaPost files, which are read as TeX
input, and therefore use the standard input mechanism).
