+Building a static binary
+------------------------
+
+It may be useful to build static binaries, for example to run in a chroot.
+
+It can be done like this at the time of writing (v0.24):
+
+cd libgit2-src
+
+# change the options in the CMake file: CMakeLists.txt
+BUILD_SHARED_LIBS to OFF (static)
+CURL to OFF (not needed)
+USE_SSH OFF (not needed)
+THREADSAFE OFF (not needed)
+USE_OPENSSL OFF (not needed, use builtin)
+
+mkdir -p build && cd build
+cmake ../
+make
+make install
+
+
+Extract owner field from git config
+-----------------------------------
+
+A way to extract the gitweb owner for example in the format:
+
+ [gitweb]
+ owner = Name here
+
+Script:
+
+ #!/bin/sh
+ awk '/^[ ]*owner[ ]=/ {
+ sub(/^[^=]*=[ ]*/, "");
+ print $0;
+ }'
+
+
+Set clone url for a directory of repos
+--------------------------------------
+ #!/bin/sh
+ cd "$dir"
+ for i in *; do
+ test -d "$i" && echo "git://git.codemadness.org/$i" > "$i/url"
+ done
+
+
+Update files on git push
+------------------------
+
+Using a post-receive hook the static files can be automatically updated.
+Keep in mind git push -f can change the history and the commits may need
+to be recreated. This is because stagit checks if a commit file already
+exists. It also has a cache (-c) option which can conflict with the new
+history. See stagit(1).
+
+git post-receive hook (repo/.git/hooks/post-receive):
+
+ #!/bin/sh
+ # detect git push -f
+ force=0
+ while read -r old new ref; do
+ hasrevs=$(git rev-list "$old" "^$new" | sed 1q)
+ if test -n "$hasrevs"; then
+ force=1
+ break
+ fi
+ done
+
+ # remove commits and .cache on git push -f
+ #if test "$force" = "1"; then
+ # ...
+ #fi
+
+ # see example_create.sh for normal creation of the files.
+
+
+Create .tar.gz archives by tag
+------------------------------
+ #!/bin/sh
+ name="stagit"
+ mkdir -p archives
+ git tag -l | while read -r t; do
+ f="archives/${name}-$(echo "${t}" | tr '/' '_').tar.gz"
+ test -f "${f}" && continue
+ git archive \
+ --format tar.gz \
+ --prefix "${t}/" \
+ -o "${f}" \
+ -- \
+ "${t}"
+ done
