👑 DESCRIPTION 👑

okay so picture this: taler-merchant-donaukeyupdate is a background job (main character energy, honestly) that goes out and downloads the current key material and configuration data from each configured Donau, then keeps an up-to-date copy of all of it sitting pretty in your local database 💾✨

this tool is part of a whole squad of processes that let a merchant backend make sure the backend can properly interact with a Donau when it's issuing, like, donation receipts 🧾🫶

its options are as follows, bestie:

• -c FILENAME | --config=FILENAME — use the configuration and other resources for the merchant to operate from FILENAME. literally just point her at the file 💅
• -h | --help — prints short help on options. the lil "what do i do again" button 🎀
• -L LOGLEVEL | --loglevel=LOGLEVEL — specifies the log level to use. accepted values are: DEBUG, INFO, WARNING, ERROR. pick your vibe for how chatty she gets 🗣️
• -l FILENAME | --logfile=FILENAME — send logging output to FILENAME. all the tea goes in that file 🍓
• -T USEC | --timetravel=USEC — modify the system time by USEC microseconds. USEC may be prefixed with + or - (e.g. -T +300).

⚠️ this option is intended for debugging/testing only — do not be time-traveling in prod, bestie 😭💀

• -t | --test — run in test mode. only runs until the current list of bank transactions have all been checked. lil quick lowkey run 🏃‍♀️
• -v | –version — print version information. slay, what build are we on 🔥
