The programs collected in /acme/edit offer a sam-like command interfaceto acme windows.  The guide file	/acme/edit/guideholds templates for several editing operations implementedby external programs.  These programs, composed ina pipeline, refine the sections of a file to be modified.Thus in sam when one says	x/.*\n/ g/foo/ pin /acme/edit one runs	x '/.*\n/' | g '/foo/' | pThe e command, unrelated to e in sam, disambiguates file names, collectslists of names, etc., and produces input suitable for the other tools.For example:	e '/usr/rob/acme:0,$' | x /oldname/ | c /newname/changes oldname to newname in all the files loaded in acme whose names matchthe literal text /usr/rob/acme. The commands in /acme/edit are	e	x	g	c	d	p	pipe	(like sam's | , which can't be used for syntactic reasons) p takes a -n flag analogous to grep's -n.  There is no s command.e has a -l flag to produce line numbers instead of the default character numbers.Its implementation is poor but sufficient for the mundane job of recreatingthe occasional line number for tools like acid; its use with the other commandsin this directory is discouraged.
