remove some env vars; make output land in html/
CLONE-URL, TITLE, and H1 are no longer processed. instead, the user
should modify the templates/default.html to their liking.
the output used to be structured like this:
target-html-directory/
+-- index.html
+-- files.html
+-- README.md.html
+-- (all the other files)
the output is now structured like this:
target-html-directory/
+-- index.html
+-- html/
+-- files.html
+-- README.md.html
+-- (all the other files...)
this makes it so people who are hosting bare repos for cloning on static
webservers will have only two new directory entries (index.html and
html) in the bare repo directory, reducing the risk of clobbering
something.
finally, i tried something hacky with gitattributes to get an automatic
version idenifier to show up. but it turns out this is not the git hash
of the commit, but instead the hash of the blob for main.scm, which
could remain the same across releases. doesn't hurt, so i'll look for a
better approach in the future.
