+.TH PROFILES 7 @VERSION@
+.SH NAME
+.B PROFILES
+- A system for a distributed HOME environment for users
+.SH SYNOPSIS
+.B "profiles-setup [options]"
+.PP
+.B "profiles-use [options] [<profile-name>|default]"
+.SH DESCRIPTION
+.PP
+The profiles system allows a user to set up, switch back and forth, and migrate
+the files comprising their "HOME" environment. It relies on a some kind of distributed
+version control system. On the initial setup, it fetches the user's desired "profiles"
+repository, which contains one or more environments -- each in its own sub-directory --
+comprising one or more files and directories. If no such repository exists and the user 
+so desires, the user's current $HOME environment will be installed as the "default" profile,
+and the repository created. Locally, profiles are stored within the user's $HOME/.profiles 
+directory.
+.PP
+To switch or install a particular profile, the user executes the "profiles-use" command,
+which will \fBreplace\fP the user's existing $HOME files and directories with soft-links
+to the corresponding files in the desired profiles subdir. To prevent the idiocy of the 
+user from destroying or overwriting desired files, the current $HOME environment is first 
+backed up. 
+.PP
+Users can override the behavior of how and which files are installed, per profile. 
+Within each profile, the .profiles directory contains several control files:
+.TP 12
+.B permissions
+File permissions are specified in the form of <octal>:<path>
+.TP
+.B nolink
+Directory entries which should be removed and re-created and file entries which should be copied instead of soft-linked. One entry per line. 
+.TP
+In the above examples, the file path is always relative to the user's $HOME directory.
+.PP
+A global configuration files, \fB@CONFIG_FILE@\fP, can be used to supply 
+defaults for the repository and version control system implementation. The user
+may provide or override such values using the \fBprofiles-setup\fP command and its prompts.
+.SH FILES
+.TP
+@CONFIG_FILE@
+contains global configuration parameters, such as the version control system and a template for the URI common to all (or most) users.
+.TP
+$HOME/.profiles
+Where all profiles are stored. Each directory within represents a "profile". All files and directories under each profile are copied or re-linked into the user's $HOME directory. (The exception is any version-control meta-information and the .profiles control files and directory.)
