Topic Branch helper tool

gistfile1.sh

#!/bin/sh
## Dialogue helper to create a "topic-branch" for cmangos

# Steps in interactive dialog:
# 1) Get name of contribution (ie LFG)
# 2) Get type of contribution (feature, fix, rewrite, cleanup)
# 3) Get short description of contribution
# 4) Get place where the topic should be published (own repo --> address)
# 5) Check current state of worktree: dirty/clean;
#     if dirty ask if changes should be taken into new topic
#     ELSE ask if topic should be forked from origin/master or current branch
# Switch to topic-branch (ie "feature_LFG")
# Create initial commit (including some suggested commit message
# 6) Edit the suggested commit message
# 7) Push to repo (check for ok)
# Create output to link to this initial commit from a sticky thread on the forum (address of commit, short description)
# And ask the user to publish this content to some sticky thread
