DATADIR added for future use \
(just to be sure that PKGBASE will be used in place of PORTNAME)
binary*.sed added to SAMP_FILES
SAMP_DIR replaced by EXAMPLESDIR
share/doc/gsed replaced by %%DOCSDIR%%
share/examples/gsed replaced by %%EXAMPLESDIR%%
Committed, thanks! While there, I converted info files
from pkg-plist into INFO macro.
