      9 mor(pheus) is tool that simplifies dependency management the right way.
     10 Some might even say it is a red-pill way of dependency management.
     11 
     12 mor searches for requirements.ini file in the current folder, and uses it's
     13 content to download files.
     14 
     15 Goals
     16 -----
     17 * Should work standalone
     18 * Cross-platform
     19 * Tiny - mor.cmd for windows, mor.sh for *NIX
     20 
     21 Note
     22 ----
     23 - Read the FAQ section
     24 - Check the Windows section below if you're using mor.cmd
     25 
     26 Config File
     27 ------------
     28 mor uses .ini files as config files and can be given to mor with -c flag.
     29 When no flags are given, it searches for requirements.ini in the current
     30 working directory.
     31 
     32 In a mor config file, the [sections] represent a directory or target.
     33 The key=value pair under the [section] are the files to download in that
     34 current directory.
     35 
     36 [$] is a special section that is discussed in 'Variables' below.
     37 
     38 	; requirements.ini
     39 	[$]
     40 	/=out
     41 
     42 	[precompiled]
     43 	libfoo-2.7=https://example.com/awavauatush/libfoo.zip
     44 	libbar-3.5=https://example.com/awavauatush/libbar.zip
     45 	...
     46 
     47 	$ mor precompiled
     48 	$ tree out/
     49 	precompile
     50 	|--libbar-3.5.zip
     51 	|--libbar-3.5/
     52 	|--libfoo-2.7.zip
     53 	|--libfoo-2.7/
     54 
     55 Targets
     56 -------
     57 
     58 Not all sections create sub-directoies mind you!
     59 
     60 Sections that have a '@' or '#' as the starting letter are treated as target(@)
     61 and target query(#).
     62 
     63 Previously we have created [precompiled] section and invoked the mor command to
     64 download it. Real life is seldom this simple.
     65 
     66 Usually we are in a situation where the pre-compiled binaries are different for
     67 different architectures and platforms.
     68 
     69 	; packages.ini
     70 	[precompiled-macos]
     71 	libfoo-2.7=https://example.com/macos/precompiled.zip
     72 
     73 	[precompiled-linux]
     74 	libfoo-2.7=https://example.com/linux/precompiled.zip
     75 
     76 In that case we can define a target query with '#',
     77 
     78 	; packages.ini
     79 	[#lib]
     80 	match=k-v
     81 	paths=precompiled-$platform download
     82 
     83 	; requirements.ini
     84 	[@lib]
     85 	libfoo=2.7
     86 
     87 The $platform in the above can be passed to mor as,
     88 
     89 	mor -Dplatform=linux @lib
     90 
     91 Variables
     92 ---------
     93 
     94 mor treats any word that starts with '$' as variable and tries to expand it.
     95 
     96 Variables in mor has a specific rule and follows the following regex,
     97 
     98 	([a-z][A-z])*[0-9][a-z]
     99 
    100 	[$]
    101 	; the output folder
    102 	/=outfolder
    103 	; arbitrary variables
    104 	git=https://git.example.com
    105 
    106 Status Messages
    107 ---------------
    108 Mor uses the following symbols to denote the status to the user,
    109 
    110 v - Download
    111 | - Archive Extraction
    112 g - Git
    113 > - Info
    114 ! - Error
    115 
    116 Example
    117 -------
    118 	; requirements.ini
    119 	[$]
    120 	>[]=packages.ini
    121 	@[]=@lib @build
    122 
    123 	[@lib]
    124 	libfoo=2.7
    125 
    126 	# when using apple-darwin, use @lib
    127 	[@lib:x86_64-apple-darwin]
    128 	libfoo-git=2.7
    129 
    130 	; packages.ini

    140 Windows
    141 -------
    142 - curl is the preferred downloader for windows, but if it is missing, mor
    143 defaults to bitsadmin.exe which is available in older versions of Windows.
    144 
    145 If you face extreme slowness in downloads when using bitsadmin, it's probably
    146 because some other application is using it to download
    147 something (like Windows Update).If you are on a hurry, you can do
    148 
    149 	C:\Users\Admin> bitsadmin /reset
    150 
    151 to clear all downloads and try running mor again.
    152 
    153 Bugs
    154 ----
    155 - Currently it is not possible to null a variable with -D in Windows.
    156 
    157 	mor -Dvar= download
    158 
    159 The above will silently assign 'download' to $var.
    160 This is a bug with how the cmd process arguments. Use -Dvar="" instead.
    161 
    162 - It is currently not possible to use a '$something' directly in a URL if a
    163 variable named 'something' is defined in '$' section
    164 
    165 - The varable expansion is not really ([a-z][A-z])*[0-9][a-z].
    166 
    167 FAQ
    168 ---
    169 > Why the weird symbols ($/, $<, $>) instead of simple clean $root, $include,
    170 etc in [$]?
    171 I wanted mor to be as language agnostic as possible and I wanted the core
    172 variables to be ASCII clean. This is also the reason why the status messages
    173 are mostly made up of symbols.
    174 
    175 > Where are the damn CHANGELOGs?
