+# Password Manager
+
+Barebones password manager with absolutely no fancy features. By
+that I mean,
+
+- No password generation
+- No git integration
+- No questions asked
+- No grepping/finding passwords
+- No clipboard support
+- No tree view
+- Does not ask for password input (reads from stdin)
+- Does not check for 'sneaky paths?'
+
+Supports adding/deleting/listing/showing passwords. I don't
+intend on implementing any more features. You can wrap this
+script with something other to make use of it. See the contrib
+directory for that.
+
+Currently less than 35 SLOC. It's almost 20 times smaller
+than `pass` which has a little less than 600 SLOC.
+
+
+To install run, as root if necessary
+
+ make install
+
+You really do think that asking for password for twice blah
+blah is a really important feature? Okay, then add a function
+to your shellrc/profile like this.
+
+ pmask() {
+ [ "$1" ] || return 1
+ printf 'Enter your password: '
+ read pass
+ printf 'Enter your password again: '
+ read pass2
+ [ "$pass" = "$pass2" ] && {
+ printf '%s' "$pass" | pm a "$1" && return 0
+ }
+ printf "Passwords don't match\n"
+ return 1
+ }
+
+You want to copy to clipboard? That's easy! You just need
+to do a `pm s passname | xclip -sel c`. You can still make
+it a function by doing this
+
+ copypass() {
+ [ "$1" ] || return 1
+ pm s "$1" | xclip -sel c
+ }
+
+The whole rationale is that you can already do that with simple
+commands. Why complicate (and possibly break) things by introducing
+them into a single script? If you want some function that is
+a must for you, implement it yourself with some script or
+a shell function. This way, it works just as you intended it. Or use
+helper functions that are located in contrib.
+
+You can install contrib scripts by running
+
+ make -C contrib install
