Emacs/Perforce integration: back from the dead

p4.el, the Emacs/Perforce Integration, provides an interface to the Perforce software version management system from the Emacs text editor. Written originally by Eric Promislow, with important contributions from Rajesh Vaidheeswarran, Peter Österlund, and many others, it’s a piece of software that I have used more or less every day for the last thirteen years. ( However, the SourceForge repository hasn’t seen any development since 2005, and it has been looking a bit ragged around the edges for a few years now. )
