add script to autogenerate help from man pages
This creates main help like: -- usage: apk [<OPTIONS>...] COMMAND [<ARGUMENTS>...] Package installation and removal: add Add packages to WORLD and commit changes del Remove packages from WORLD and commit changes System maintenance: fix Check WORLD against the system and ensure consistency update Update repository indexes upgrade Install upgrades available from repositories cache Commands related to the management of an offline package cache Querying package information: info Give detailed information about packages or repositories list List packages matching a pattern or other criteria dot Generate graphviz graphs policy Show repository policy for packages Repository maintenance: index Create repository index file from packages fetch Download packages from global repositories to a local directory manifest Show checksums of package contents verify Verify package integrity and signature Miscellaneous: audit Audit directories for changes stats Show statistics about repositories and installations version Compare package versions or perform tests on version strings This apk has coffee making abilities. -- And applet specific help like: -- usage: apk add [<OPTIONS>...] PACKAGES... Description: apk add adds the requested packages to WORLD and installs (or upgrades) them if not already present, ensuring all dependencies are met. Options: --initdb Initialize a new package database -l, --latest Disables normal heuristics for choosing which repository to install a -u, --upgrade When adding packages which are already installed, upgrade them rather -t, --virtual NAME Instead of adding the specified packages to WORLD, create a new --no-chown Do not change file owner or group --cute-signatures

Utility to convert SCDOC manpages to apk-tools help messages
|
||||
|
||||
General:
|
||||
- Wrangle *apk-applet*(SECTION) links
|
||||
- Uppercase _underlined_ things as they are "keywords"
|
||||
- Other format specs like ** to be removed
|
||||
- For options text, the first sentence (within the first line) is taken as the help text
|
||||
|
||||
Main page: apk.8.scd
|
||||
- SYNOPSIS
|
||||
- COMMANDS has ## header with a table for commands list
|
||||
- GLOBAL OPTIONS and COMMIT OPTIONS for option group help
|
||||
- NOTES
|
||||
|
||||
Applet pages: apk-*.8.scd
|
||||
- Take usage from SYNOPSIS, can have multiple lines like apk-version(8)
|
||||
- Take DESCRIPTION, take first paragraph, rewrap, and put as section in applet specific help
|
||||
- From OPTIONS take each option and it's first sentence (within the first line)
