svn-to-git

Migrates multiple SVN repos to GitHub, without anything fancy (no Ruby, no dependencies, no issues with Cygwin paths). SVN tags are created as Git tags and properly pushed to GitHub. To run:

1) Edit run-authors.sh to have your SVN repos. Run it to get an authors.txt file.

2) Edit the authors.txt to have GitHub names and emails if you like. You must use GitHub user email addresses if you want contributions to be associated with GitHub accounts.

3) Create the GitHub projects, without populating it with a readme or license.

4) Edit run-convert.sh to have your SVN repos, GitHub user URL, and GitHub project name. Run it.

5) Done!

cp authors.txt authors.temp
svn log -q $1 | awk -F '|' '/^r/ {sub("^ ", "", $2); sub(" $", "", $2); print $2" = "$2" <"$2">"}' | sort -u >> authors.temp
cat authors.temp | sort -u > authors.txt
rm authors.temp
