"""
3+
Python script to generate a man page for the command `fastfetch`.
4+
The man content will be printed to stdout so you will need to
5+
pipe it to a file if you want to save it.
6+
The command options will be generated using a JSON file.
7+
For the format of the JSON file, see https://github.com/fastfetch-cli/fastfetch/blob/dev/src/data/help.json

.SS Fetch Structure \n\
69+
The structure of a fetch describes the modules that should \
70+
be included in the output. It consists of a string of modules, \
71+
separated by a colon (:). To list all available modules, \
72+
use --list-modules \
73+
\n\n\
74+
.SS Config Files \n\
75+
Fastfetch uses JSONC based format for configuration. \
76+
Fastfetch doesn't generate config file automatically; \
77+
it should be generated manually by {startBold}--gen-config.{endBold} \
78+
The config file will be saved in \
79+
{startBold}~/.config/fastfetch/config.jsonc{endBold} by default. \
80+
\n\n\
81+
A JSONC config file is a JSON file that also supports comments \
82+
with (// and /* */). Those files must have the extension '.jsonc'. \
83+
\n\n\
84+
The specified configuration/preset files are searched in the following order: \
85+
\n\n\
86+
{startBold}1.{endBold} relative to the current working directory \
87+
\n\n\
88+
{startBold}2.{endBold} relative to ~/.local/share/fastfetch/presets/ \
89+
\n\n\
90+
{startBold}3.{endBold} relative to /usr/share/fastfetch/presets/ \
91+
\n\n\
92+
Fastfetch provides some default presets. List them with --list-presets. \
