+# NAME
+#	enter 1
+# SUMMARY
+#	set up a project-specific environment
+# PROJECT
+#	sdetools
+# SYNOPSIS
+#	enter project
+#	exit
+# DESCRIPTION
+#	The \fIenter\fR command sets up an environment that makes
+#	it easy to access \fIproject\fR-specific programs and files.
+#
+#	\fIenter\fP consults a file with environment information
+#	($HOME/.\fIproject\fR, Bourne-shell syntax) and invokes 
+#	a new command shell of the same type as the login shell.
+#	Typically, project environment files are maintained and 
+#	given out by the project administrator.
+#
+#	In order to leave the project environment use the \fIexit\fP 
+#	command or type a control-d;
+#	the details may depend on the type of login shell involved.
+#
+#	As a minimum, the environment file should set an environment
+#	variable with the same name as the \fIproject\fP. The variable 
+#	name can be either be identical to \fIproject\fP or in upper case.
+#	For consistency, \fIenter\fP will set both variables to the same value.
+# EXAMPLE
+# .fi
+# .ad
+#	In this example, 
+#	all files pertaining to a project \fIfoobar\fR are located under the
+#	directory \fI/usr/foo/bar/foobar\fR. For example, there
+#	are subdirectories
+#	\fI/usr/foo/bar/foobar/man\fR with manual pages, 
+#	\fI/usr/foo/bar/foobar/bin\fR with executable 
+#	programs, other directories for object libraries and include files, 
+#	and so on.
+#
+#	In order to enter a project \fIfoobar\fR, the command
+# .PP
+# .ti +5
+# .ft C
+#	enter foobar
+# .ft 
+# .PP
+#	consults a file \fI.foobar\fR (in the user\'s home directory) 
+#	with contents:
+# .PP
+# .ft C
+# .nf
+# .in +5
+#	export FOOBAR;	FOOBAR=/usr/foo/bar/foobar
+#	export PATH;	PATH=$PATH:$FOOBAR/bin
+#	export MANPATH;	MANPATH=$MANPATH:$FOOBAR/man
+# .ft 
+# .fi
+# .PP
+#	The second line automatically makes all project-specific 
+#	executable programs accessible. The third line makes it possible 
+#	to use the standard UNIX \fIman\fR command for retrieval of 
+#	project-specific manual pages. The \fIenter\fR command
+#	makes sure that both the \fIfoobar\fR and \fIFOOBAR\fR
+#	environment variables are set to the same value.
+# COMMANDS
+#	sh(1), echo(1), test(1), tr(1), login shell
+# FILES
+#	$HOME/.\fIproject\fR
+# ENVIRONMENT VARIABLES
+#	SHELL, login shell
+#	HOME, login directory
+#	PATH, search path for commands
+#	MANPATH, search path for the \fIman\fR command.
+# BUGS
+#	Name clashes may occur if people have entered several projects
+#	at the same time. This can be avoided by using unique project names,
+#	which is a good idea anyway.
