HLaTeX is a LaTeX package to use Hangul (Korean Character) with LaTeX, written by Koaunghi Un. It contains macro files, configuration files, and fonts. Most Korean TeXnician use it, and there is a debian package of it. And here is a gentoo ebuild. It downloads HLaTeX from cvs repository and copy it. And it changes setting files automatically, instead of telling users how to change them. ebuild is somewhat dirty, but it worked fine. This ebuild is based on a FAQ of KTUG, Korean TeX User Group.
Created attachment 31660 [details] /usr/portage/dev-tex/hlatex-cvs/hlatex-cvs-0.0.ebuild Ebuild file. I used version number 0.0 for testing. Its actual version is 0.991.
Created attachment 31661 [details] /usr/portage/dev-tex/hlatex-cvs/hlatex-cvs-0.0.ebuild Just the same file, but plain text, not octet stream. Again, its actual version is 0.991.
It contains comments which can be removed. They explain what this ebuild does.
Created attachment 37906 [details] dev-tex part of the portage which contains hlatex and hlatex-cvs I modified ebuilds.
Sorry for the delay. I modified your ebuild a little (we don't put files bigger than 20k into ${FILESDIR}, so I tarred up uch-dvipdfmx.map and uhc-pdftex.map and put it on gentoo mirrors.) and committed. Thanks for the contribution. I'm not going to add cvs version of it since I cannot guarantee hlatex-cvs working. If cvs version contains important fix for a bug or major function improvement, please consider making a CVS snapshot instead of a live CVS ebuild.
