I understood how to install Mercurial and how to use it in a few minutes. - Giorgos Keramidas Just works the way I expect - Paul Moore It took me one evening to get comfortable with it. About a month to better understand its distributed nature. - Isaac Jurado [Mercurial] can be configured to support either simple environments or very complicated streams of changes interacting in custom ways, and it does all that without becoming a humongous monster of complexity. - Giorgos Keramidas The dev's of Hg are generally friendly and approachable. - Gerard Korsten The code base for Hg is pretty small and yet its pretty feature complete. - Gerard Korsten Simplicity, being distributed, extensibility, speed, familiarity, bash completion, understandable and reasonably small code base - Peter Arrenbrecht The team on the project gradually grew from just me to a few people here and abroad. This was a totally seamless experience - Peter Arrenbrecht Easy to understand at a practical level. - Michael Estrand The included web server [...] replaces a lot of functionality of GUI tools in a truly multiplatform way. - Daniel Serpell There isn't much to learn to be effective. - Doug Philips It took my less than an hour to understand it. - Thomas Burdick It has a tortoise so I can actually show my boss it's highly productive even in windows. - Thomas Burdick The commands usually do what I assume them to do. - Bastian Doetsch Mercurial's conceptual model is clean and simple enough to carry around in my head. - hgbook It's so easy to start a project; hg init, and you're good to go. - Paul Fisher It simply works [...]. - Hans Meine Mercurial offers an excellent "sweet spot" in terms of flexibility, simplicity, and speed. - Alex Martelli, Google Tech Lead. These days, Mercurial is what my wife Anna and I use for all new personal projects, and all open-source and community projects where it's an option. - Alex Martelli, Google Tech Lead.
