+Usage:
+  pwgen [OPTIONS]
+
+Application Options:
+  -a, --disable-alpha            If specified, do NOT include the Alphabetical (letter) charset.
+  -n, --disable-num              If specified, do NOT include the Numerical (number) charset.
+  -s, --disable-symbols          If specified, do NOT include the Simple Symbols charset.
+  -S, --enable-extended-symbols  If specified, include the Extended Symbols charset (these characters may cause issues in some applications).
+  -u, --count-upper=             The number of minimum uppercase characters. If not specified, this is random (if in the charset).
+  -U, --count-lower=             The number of minimum lowercase characters. If not specified, this is random (if in the charset).
+  -N, --count-numbers=           The number of minimum number characters. If not specified, this is random (if in the charset).
+  -y, --count-symbols=           The number of minimum simple symbol characters. If not specified, this is random (if in the charset).
+  -Y, --count-extended=          The number of minimum extended symbol characters. If not specified, this is random (if in the charset).
+  -d, --disable-chars=           If specified, these chars should be explicitly excluded from the charset(s). Can be specified multiple times with multiple chars per switch.
+  -e, --explicit-chars=          If specified, ignore all charset selection and only use these characters to select from. Can be specified multiple times.
+  -l, --min-length=              The minimum length for passwords; use 0 for no minimum limit. Set this to the same as -L/--max-length to use a fixed length. Must be <= -L/--max-length. (default: 16)
+  -L, --max-length=              The maximum length for passwords; use 0 for no maximum limit (this is hard-capped to 256 for performance reasons). Set this to the same as -l/--min-length for a fixed length. Must be >= -l/--min-length.
+                                 (default: 64)
+  -c, --count=                   The number of passwords to generate. (default: 1)

 ## What it Doesn't Do
 PWGen does not, and will not, generate "Correct Horse Battery Stapler" passphrases (as demonstrated in [XKCD #936](https://xkcd.com/936/)).
