🧚 Flags 🧚

• -s — Update range. that's it. that's the whole flag.

• --quiet — Quiet module output. she goes silent. mysterious. iconic.
• --ui — Force launching GUI dialog. for the visual girlies.

🍓 Parameters 🍓

• history=phrase — Text to append to the next line of the map's metadata file.
• unit=string — The map data unit.
• vunit=string — The vertical unit of the map.
• source1=phrase — Text to use for data source, line 1.
• source2=phrase — Text to use for data source, line 2. (yes there are two. she needed a part two.)
• description=phrase — Text to use for data description or keyword(s).

💅 DESCRIPTION 💅

so <hotpink>r3.support</hotpink> allows the user to create and/or edit raster3d map support information. the way that it edits raster3d map units, history, description and title… obsessed. that's the whole job, and she does it flawlessly.

⭐ NOTES ⭐

Freeform metadata info lives in a "hist" file, and you can keep appending to it with the history option. important though: currently this is limited to text with a maximum line length of 78 characters. any input larger than that gets wrapped onto the next line — no drama, it just folds over. and all the other metadata strings available as standard options? those are limited to 79 characters. 79, bestie. not 80. do not test her.
